Wow, that sucks. I know this can be an issue in male-dominated areas such as homebrewing, but just to provide another female brewer data point, they've always been very nice to me, to the point that I consider one of them and his fiance friends now.

Back when I was a lot hotter and studied & worked in another male-dominated field full of guys with poor social skills (computer science), I used to see a lot more of that.
