Why do parents basically condone teenage pregnancy?? My bf and I were talking about this?

No, I agree with you. I would be the same way if I had a teen daughter who got pregnant and was silly and naive enough to want to keep the baby. If she chose to have an abortion early on or have the baby and give it up for adoption I would support her and help pay for the abortion or help her find adoptive parents. If she wanted to keep the baby though she would be out on her own. If you want to do adult things you can act like an adult and support yourself IMO.
