There are two types of people who don't like Planned Parenthood:
1) People who are opposed to sex ed, contraception, and abortion. It's pretty obvious why this sort of person would not be a Planned Parenthood fan. From their point of view, Planned Parenthood has no redeeming qualities. I'm sure there are probably a few posters on this forum who fall into this category, but I don't get the impression that there are very many. Admittedly, it is FBG that is kind of out whack here. Obviously there are lots of evangelicals and social conservatives out there in the real world, but they're underrepresented here.
2) People who are fine with sex ed and contraception, but oppose abortion. I'm in this category. If Planned Parenthood just did birth control and non-abortion-related health care, I'd be happy with it. People like me probably (just a hunch) make up a minority of the anti-Planned Parenthood brigade, but we're relatively over-represented here. I think that's the main reason why nobody is chiming in on this one with any serious questions. For us, going to Planned Parenthood to get a vasectomy (or a pap smear, or an IUD) isn't materially different than going to our doctor for an annual check-up, complete with jokes about our doctor getting way more familiar with us than we would like.
