I've run into surprising misinformation about the prolife side of things. I spoke with somebody in passing who didn't know that most prolife organizations support exceptions for the life of the mother, rape, and incest.

If most of the folks you hang out with online are fellow prochoice types, you might never run into the ones who go trolling on sites where prolife types are likely to hang out. However, you might attract other types of trolls. It's easy to assume that the only rude people are the ones on the other side of the debate, if that's the only part of it you ever experience.
