Stumbled on this yesterday, but didn't want to be the one to bump it. But since it's here...
I lurk a lot, and post only occasionally. I've seen some misogynist (and/or homophobic and/or transphobic) jerks on occasion (usually several year old posts, so maybe it's changed over time). It makes me uncomfortable, but I've also noticed that, 98% of the time, said jerk gets roasted by someone else for the comment. Other rudeness gets taken care of by a mod. I feel comfortable knowing that if I ever needed to hit the report button, it would result in a positive change. That means a lot to me.
I have never had that sort of atmosphere at a place like reddit, so a different result there makes complete sense.
I've never been treated poorly for my gender on this site, nor in most spaces for brewing. There's one guy at one of the HBS's near me who's rude to me, but I think he's that way to just about everybody, so I don't think it's a gender thing. And at another LHBS, I'm known by name and treated very well. This is also in metro Southern California, so it may be different at other places.
Just my two cents. TL;DR Version: Love it here at HBT, misogyny is probably a problem in some other brew spaces, but I don't think it's a big issue here.
