Don't take this to mean that I think I can say/do whatever I want in this industry on account of being female -- no one is bulletproof. It just seems men are vilified more than women when it comes to these sorts of things. Maybe that's just my world view.
For the tech-world, I guess a black lesbian would be a triple-concern? I would say that is a problem. Not sure how to fix it, but that's a problem. I personally don't have to change my behavior or speech when a lady is in the room. But then again, I'm probably unique in that... I never, ever use profanity and never make jokes that wouldn't be safe on the Disney channel. I don't know anyone who can claim that besides me. But, I will say compared to my time at at&t... the men there seemed to be less frat-housey than the SV-startup-culture. The men at at&t seemed to be more "gentlemanly", more socially acceptable. SV-startup-culture I think allows the frat-house/bro-grammer attitude to grow thus making it more difficult to the men who are use to that to clean up when a lady is around. At least, that's what I've seen.
It's not just a tech problem either. This stuff is going on all around the world. I don't claim to have solutions to these problems, but I would appreciate it if the public shaming and witch hunts would stop. I'm tired, SV. So very tired.
I've never worked at AT&T but I'd wager the same stuff went on. Perhaps you experienced the same sort of thing I did where people assumed you wouldn't appreciate their words/actions and elected to avoid you?
