I know I'm probably wrong here, and I'm willing to be better informed, but I don't like the phrasing of abortion as mere "birth control," as if it were equal to methods that prevent conception or implantation.
Do people really feel it's not a different sort of act, or would people be comfortable using abortion as their sole means of birth control (if it were safe and inconsequential to the woman)? And yes, I understand that the morning after pill is something of a gray area.
Also yes, I am a Christian. But I understand that there are good reasons for abortion remaining legal.
