But you weren't targeted for this behavior due to your gender identity or skin color, and you more or less started off with "I don't think your issues as a Black person/as a woman have been that bad because my experience hasn't been bad." Like you immediately centered yourself in a discussion about other people, and have done nothing to show any effort to even hear what they're saying.
Additionally, one person's positive anecdotes do not outweigh another person's negative anecdotes. If I'm thinking about joining some arbitrary group of people and most of my friends say it's a good time, but even one person says "I showed up and all the men either sexually harassed me for being female or witnessed the harassment and did nothing about it", well, that tells me a lot more than the other person who says "They kind of joke around a bit but it's really a mostly positive place!"
Being roasted for being a moron was something where it was/is allowed to stand up for yourself. I know that when people thought I was male, I was allowed to give as good as I got as long as I knew how to take an L once in a while and had a thick skin. Arguing and insulting back is accepted and a lot of the arguments can be conclusively settled in some way. Even if you pedantically argue for something incorrect long after you should, you can usually make amends by accepting you acted like a dumbass and letting people clown on you for it.
The shit I got for being female was different because it was a bunch of projection that I had no way of addressing. There are a lot of people who are just plain not okay with the opposite sex and could not handle being turned down. The most vile crap was spewed in private and then it turned into 'he said/she said' or 'I/we can't control what members say or do outside of the channel/forum/newsgroup'. Ambient sexist atmospheres could not be diffused by giving the guff back as places that are 90/10 male to female do not respond well to the women clowning on the men: You can't answer 'get back in the kitchen and make me a sandwich' with 'get back to the factory and make me money' because the men fall in line to support each other. You can't answer it by bringing it up seriously because then you're a buzz kill, etc. It's not two equals arguing; it's one side being told to shut the fuck up.
