Please, I mean no offense by this answer. It is harsh, it is sad, but it is the way that it is and should be in my view.
"What other reasons would there be?" "why would anyone want to have an abortion?"
Because I want to. Because I don't want the baby. Because I'm a selfish a-hole (in some cases). Irrelevant. It is MY body, it is MY decision.
Again, I apologize, but there is no better reason. It is sad that some women use abortion as a means to birth control. But it is their body. Their decision. So let's try to take another angle to fix this problem. Because in my view, you can't dare force somebody to do something they don't want to do with their own body. Right, wrong, good or bad.
