I think most of the real answers have already been offered up, most notably anonymity on the internet. Plus, much to my surprise initially (15 years ago, or so) there is a surprising amont of misogyny among hobbyists. It's certainly not universal, but it's far more than I would have expected. Plus, some folks who participate on both sides of the hobby just aren't worth a shit at dealing with people, love drama, or just have too much fucking time on their hands. Some never got out of the junior high school mind set. Some don't' have a life outside of ECCIE.
But I don't seem to attract too much controversy, and controversy doesn't seem to follow me. So there is something you can do about it. Probably harder to do something about it as a provider, but it's probably not impossible to do something to at least reduce the drama. Probably a few folks that are constitutionally incapable of reducing the drama. And that shouldn't be -- but probably is -- a surprise to those folks. C'est la vie!!
