Yes, it's pretty oblivious that a fetus has parasitical functions, it needs time to develop it's own body functions, blah blah blah. A point of nuance being that the mother body has parts meant specifically to host it, so don't be all dramatic''IT STEALS HER NUTRIENTS'' about it. All mammals are like this, and other species that don't just stick the zygote into a shell with all the nutrients provided. Easy biology.
Now, what do you want to WANT with this simple conclusion? And write it yourself please, since this what we actually discuss here about abortion.
