This argument doesnt really work, because if you had never been born, it wouldn't matter. You wouldn't know what life was like because you'd never had one.

Aborting a fetus for any reason is not "wishing people like you had never been born." It's wanting children to be able to grow up in a loving environment that is prepared for it, and allowing women to decide if their environment is right without interference from others.

Also, just because you survived a harsh upbringing doesn't mean that you should be advocating for parents to raise a child in a similar way. Ideally, no child should be born in a bad environment. Once they are born it's a different story.
