i have 2 friends that have had abortions. one was with a total dirt bag that treated her like shit, so having a baby with him would have ruined her and the baby's lives. the second friend was totally not prepared for a baby. she wouldve had to quit college and all that.
i dont think abortion should be used as a contraceptive, but i do think it should be legal to make the choice. sometime people get drunk at a bar and end up goin home with someone and havin sex. shit happens and people get pregnant. the brain doesnt always think about the consequences 9 months down the road when it is in a sexually charged state.
i also agree with what ganjames said about population. if i ever got a girl pregnant, id probably try to talk her into an abortion, to be honest(although i always use condoms). if i ever wanted a kid, i would definitely adopt. there are TONS of kids that have nobody. my dad was adopted too, so thats another reason why.
