It's a total boys club. I would have expected that people who self identify as progressive/liberal wouldn't treat me like I'm less than human, but I was wrong about that too. Maybe it's the state where I live, my town is famous for being host to a big white supremacy rally a few years back (you may be able to guess) and people are just awful here. But I've heard reports of harassment and discrimination from trans women who live in blue states all the same.
I should add, I am lucky enough to be working with a wonderful group of people, who are the most accepting and supportive people in my life right now.. but that's just the small team I'm working with, I was in a different part of my organization before coming out and I did not feel like I could transition while working with those people. My old boss was coming from a liberal ivy league university in a blue state, and he turned out to be a huge misogynist/xenophobe. People make jokes all the time that they think are "no big deal" and they don't seem to understand at all how hurtful words can be when you're facing harassment, hostility, threats from total strangers all day long.
I am glad that you finally found a safe workplace to work and people who accept you as you are. Feel sad to hear that tech is a "boys club" it shouldn't be this way. If you don't feel safe where you work how can you function properly in society, where you may face rejection and hostility. This is so wrong.
