This is gonna sound insane, as I am conservative as fuck in almost every plausible way, but I am actually pro choice up until a certain point. I would say anything after 20 weeks seems excessive, as the mother has literally had 5 fucking months to think about it! The only exceptions to this rule should be if she finds out her pregnancy could possibly be dangerous to her own life. If that is the case, she should be able to have the abortion is soon as the doctor deems it dangerous to her own life, regardless to how late it is in the pregnancy. As I view the mothers life to be more important to someone unborn.
In all other cases, the mother should know the FULL details of what is going to occur to her child, and how much horrific pain they will be in! As I highly doubt that the majority of late term abortions are done because of risk to the mother. More likely it is because she is scared to be a single mother and have no money. Just give birth and put it up for adoption! If the baby is from a white mother who isn't a crack whore, you will have hundreds of familys begging to adopt your child.
