As somebody who finds the left and right both extraordinarily cringe, I gotta say it's pretty silly when you folks have the same logic. You sound exactly like the pro-choice people who say "I can't wrap my head around how some anti-choice people think that it's okay for the government to control women's wombs."
I mean, seriously? Pro-life people think life begins at conception, and therefore abortions are killing a living human, which is wrong. Pro-choice people think that life begins later, and therefore performing an abortion before that later point is no different from removing a cyst or any other growth. Is that really that difficult to understand?
I can respect people on either side, and I won't pretend to have the perfect answer for when a sperm cell and an egg become a human being, so I can appreciate both arguments. But, it's frankly embarrassing to pretend you "can't wrap your head around" the other side of the argument. Do you think you're winning the argument by pretending to be retarded? It's the simplest damned argument in the world to see both sides of. One side thinks that a fetus is a human, one does not. Whichever side you agree with, can you really be so dense as to not understand the other side?
