I disagree. I've known some of these people. They are sincere and thoughtful, it's just that they've got a severe case of bias that causes them to hold contradictory evidence to an absurdly high standard, while blindly accepting anything that agrees with them. These people are used to being shouted down, banned, and publicly mocked, which just feeds into their persecution complex. They can be reasoned with, but it's laborious, unpleasant, and not really worth my time. That's not to say there aren't quite a few regular trolls - but anecdotally, I don't think trolls are the majority.
