I'M SICK N' TIRED OF YOUR PRO-LIFE-SCHIZOPHRENIC-FASCISM AND YOURLIES.

Libertarians for Life - Why the Embryo or Fetus Is Not a Parasite is a sham, pro-life-schizophrenic-fascist site...here's why (written as a response from a forum):

"1. a) A parasite is defined as an organism of one species living in or on an organism of another species (a heterospecific relationship) and deriving its nourishment from the host (is metabolically dependent on the host). (See Cheng, T.C., General Parasitology, p. 7, 1973.)"

Wrong, like I posted before:

‘"It is also possible for a symbiotic relationship to exist between two organisms of the same species."

http://www.answers.com/topic/symbiosis -- Gale's Science of Everyday Things.

just like a parasitic twin --- http://en.wikipedia.org/wiki/Parasitic_twin

"an animal or plant that lives in or on another (the host) from which it obtains nourishment. The host does not benefit from the association and is often harmed by it"

http://www.thefreedictionary.com/parasite

your site omitted symbiotic intraspecific relationships, like parasitic twins and the woman/fetus relationship:

“When individuals of the same species parasitize individuals of the same species, they are referred to as intraspecific parasites.”

http://krohde.wordpress.com/article/parasitism-an-introduction-to-xk923bc3gp4-51/

"This homospecific relationship is an obligatory dependent relationship, but not a parasitic relationship."

LOL! THAT SENTENCE RIGHT THERE PROVES THE FETUS IS A PARASITE:

"obligate parasite (obligatory parasite) one that is entirely dependent upon a host for its survival."

"2. a) A parasite is an invading organism -- coming to parasitize the host from an outside source. (b) A human embryo or fetus is formed from a fertilized egg -- the egg coming from an inside source, being formed in the ovary of the mother from where it moves into the oviduct where it may be fertilized to form the zygote -- the first cell of the new human being.

THE ZYGOTE IS A FOREIGN OBJECT ( A NEW ORGANISM) TO THE WOMAN'S BODY BECAUSE OF THE MAN'S DNA.

Why do you think the zygote has to invade the woman’s body with its TROPHOBLAST CELLS and then,  hijack the woman’s immune system to survive?

http://galerouth.blogspot.com/2012/02/welcome-to-enlightenment-enjoy.html --- to see how the human fetus is a parasite according to science.

"an animal or plant that lives in or on another (the host) from which it obtains nourishment. The host does not benefit from the association and is often harmed by it"

http://www.thefreedictionary.com/parasite

3. a) A parasite is generally harmful to some degree to the host that is harboring the parasite. (b) A human embryo or fetus developing in the uterine cavity does not usually cause harm to the mother, although it may if proper nutrition and care is not maintained by the mother.

4. a) A parasite makes direct contact with the host's tissues, often holding on by either mouth parts, hooks or suckers to the tissues involved (intestinal lining, lungs, connective tissue, etc.).
b) A human embryo or fetus makes direct contact with the uterine lining of the mother for only a short period of time.

Well, that’s just fucking stupid-- the time span shouldn’t matter, but its actions reaction relating to the woman’s body. Again, you just proved the human fetus is a parasite; anyways, google the function of TROPHOBLAST CELLS.

It soon becomes isolated inside its own amniotic sac, and from that point on makes indirect contact with the mother only by way of the umbilical cord and placenta.

WELL, THAT'S STUPID BECAUSE THE PLACENTA IS PART OF THE FETUS!

5. a) When a parasite invades host tissue, the host tissue will sometimes respond by forming a capsule (of connective tissue) to surround the parasite and cut it off from other surrounding tissue (examples would be Paragonimus westermani, lung fluke, or Oncocerca volvulus, a nematode worm causing cutaneous filariasis in the human).
b) When the human embryo or fetus attaches to and invades the lining tissue of the mother's uterus, the lining tissue responds by surrounding the human embryo and does not cut it off from the mother, but rather establishes a means of close contact (the placenta) between the mother and the new human being.
YOUR ARTICLE ADMITTED THAT THE FETUS INVADED!

I LIKE I SAID BEFORE: The placenta functions as an immunological barrier between the mother and the fetus, creating an immunologically privileged site. For this purpose, it uses several mechanisms:

It secretes Neurokinin B containing phosphocholine molecules. This is the same mechanism used by parasitic nematodes to avoid detection by the immune system of their host.[2]"

http://en.wikipedia.org/wiki/Immune_...e_in_pregnancy

" Due to its highly-negative charge, hCG may repel the immune cells of the mother, protecting the fetus during the first trimester. It has also been hypothesized that hCG may be a placental link for the development of local maternal immunotolerance."

"The woman’s immune system can attack the embryo and placenta via attack T-cells, blood complement, and antibodies. The embryo signals the placenta to produce INDOLEAMINE 2, 3-DIOXYGENASE, which catabolizes the tryptophan in the woman’s body. Starved of this necessary amino acid, the attack T-cells have to go into latency to survive, though the woman’s blood complement and antibodies can continue to attack."

THE SEARCH FOR LINKS BETWEEN IMMUNOGENETIC FACTORS AND RECURRENT MISCARRIAGE.

 “Decidual macrophages produce IL-10 and tryptophan catabolizing enzyme indoleamine 2, 3-dioxygenase (IDO) (Heikkinen et al. 2003). IDO is one of those molecules that may suppress maternal T-cell activation. Inhibition of IDO in mice, especially in allogeneic mating combinations, results in fetal rejection with lethalinflammatory response, with T-cell infiltration and activation of complement. “

6. a) When a parasite invades a host, the host will usually respond by forming antibodies in response to the somatic antigens (molecules comprising the body of the parasite) or metabolic antigens (molecules secreted or excreted by the parasite) of the parasite. Parasitism usually involves an immunological response on the part of the host. (See Cheng, T.C., General Parasitology, p. 8.)
b) New evidence, presented by Beer and Billingham in their article, "The Embryo as a Transplant" (Scientific American, April, 1974), indicates that the mother does react to the presence of the embryo by producing humoral antibodies,but they suggest that the trophoblast -- the jacket of cells surrounding the embryo -- blocks the action of these antibodies and therefore the embryo or fetus is not rejected. This reaction is unique to the embryo-mother relationship.

SO LIKE A PARASITE,  THE ZYGOTE HAS MECHANISMS TO STOP IT FORM BEING KILLED, BECAUSE IT'S A FOREIGN OBJECT AND AN INVADER.

7. a) A parasite is generally detrimental to the reproductive capacity of the invaded host. The host may be weakened, diseased or killed by the parasite, thus reducing or eliminating the host's capacity to reproduce.
b) A human embryo or fetus is absolutely essential to the reproductive capacity of the involved mother (and species).

DUH!

The mother is usually not weakened, diseased or killed by the presence of the embryo or fetus, but rather is fully tolerant of this offspring which must begin his or her life in this intimate and highly specialized relationship with the mother.

WOW, THAT'S A COP-OUT, READ THE LINKS THAT I ALREADY POSTED. WTF, ARE THE RF-FACTORS PROBLEMS ABOUT?

8. a) A parasite is an organism that, once it invades the definitive host, will usually remain with host for life (as long as it or the host survives).
b) A human embryo or fetus has a temporary association with the mother, remaining only a number of months in the uterus.

“parasite [par´ah-sīt] 1. a plant or animal that lives upon or within another living organism at whose expense it obtains some advantage; see also symbiosis. Parasites include multicelled and single-celled animals, fungi, and bacteria, and some authorities also include viruses.Those that feed upon human hosts can cause diseases ranging from the mildly annoying to the severe or even fatal. (See accompanying table.)

Types of parasites.

2. parasitic fetus.

adj., adj parasit´ic.accidental parasite one that parasitizes an organism other than the usual host.

facultative parasite one that may be parasitic upon another organism but can exist independently.

incidental parasite accidental parasite.

malarial parasite Plasmodium.

obligate parasite (obligatory parasite) one that is entirely dependent upon a host for its survival.

periodic parasite one that parasitizes a host for short periods.

temporary parasite one that lives free of its host during part of its life cycle.”

That was easy! Just remember:  The pro-life-schizophrenic-fascist movement has no logical argument to keep women from aborting their unwanted fetuses.  In reality, it's their morality vs. the woman’s morality and instincts to protect her self-interest. Their movement is only based on intellectual dishonesty and the following fallacies: appeal to emotion and appeal to authority using the judeo-christian god (that they can’t even prove is empirically real)…so these fascists have no argument against SCIENCE.
