Back to the original point of this thread:
I think many people become pro-life because they get brainwashed by the fake pictures paraded around by shady pro-lifers. When they think about abortion, they picture an actual baby being ripped to shreds in an abortion clinic.
Then they wonder what kind of monster could want that done to their own baby, so they begin to hate the women who abort.
The odd thing is, no matter how educated they become on the subject, like learning that no baby is involved in abortion, and in the majority of the cases there is no fetus either, just a tiny, tiny embryo that is barely visible, the fake images of babies being killed still persist in their minds when they hear the word "abortion".
