I don't think you're getting where I'm coming from. Admittedly, my interest in ob/gyn is partially political. Women do have a legal right to have abortions, and that is obstructed by the lack of providers. IMO, that's a plus for pursuing ob/gyn. I have other reasons why I'm interested in it -- mainly that I would like the population I'd be serving. Of course, I haven't started medical school yet, so I don't know, I might hate it. However, if I do become an ob/gyn or go into fp (not considering that one, but it could happen), I expect to be trained on providing abortions. To me, I wouldn't be able to serve my patients' critical needs if I couldn't perform an abortion.
As an aside, if I go into ob/gyn, I'm also going to be actively involved in other reproductive health issues such as access to birth control and education about sexual issues. I would like to see fewer abortions, not because women just don't have the option of getting them but because they have reliable options to avoid getting pregnant. Abstinence-based sex ed and blocking of things like plan b otc are impediments to reducing unwanted pregnancies, imo.
