I had a mentor at a college internship request I be transferred to another mentor a couple days after they learned I was atheist. The ~50 person software dev org I was in was 90% male, 90% white in a >60% Black city.
For context, I'm a tall, straight-passing white dude with a slight Southern accent. I'm a guy who has had people tell me racist jokes unprompted because they assume they're in good company, and I could still see this kinda shit around me. Shit's unreal as a woman or person of color.
This was at a Fortune 50 company with a couple thousand IT/engineering employees (and this was <36 months ago).
I get that the Bay Area is not always the progressive paradise it pretends to be, but "California == liberal" in many non-West-Coast eyes for a reason.
