Fact: You are arguing about biology. You're arguing about biology that you have shown you do NOT even understand.
Fact: You don't comprehend the difference between a foetus and a baby.
Fact: A foetus cannot live OUTSIDE it's mother's womb. It cannot BREATHE, it cannot THINK, it cannot SURVIVE. Although you might not like the concept of a foetus being a parasite, that is what it certainly is. It depends upon a host for survival. A BABY can live outside the womb, UNAIDED. It can breathe on its own, cry, move its limbs, and has limited communication. Of course, it still needs someone to feed it, hold it, clean it, and change it. However, ANY human being (or even a trained monkey in cases) can take care of it after it is born. I'd love to see you try and breast-feed a gelatinous clump of cells. Fuck's sake.
Quite obviously, you DIDN'T read the link I provided - because that link mentions NOTHING about parasites. Which makes me wonder as to how high your level of reading comprehension is... especially if you cannot understand the difference between a foetus and a baby.
And you seem unable to explain to me why a group of cancerous cells (which, by your definition is alive) and a foetus (before 20 weeks gestation) is different??? Why should cancer be allowed to be obliterated, but other cells that are dependent on a host have the right to keep growing? I think you're far out of your depth and your arguments are based on how you FEEL - not actual logic or thinking.
