Here's my personal anecdote that supports this.
I live in Pennsylvania, which is considered a swing state, but it did vote for Trump both of the times he won. Pretty humiliating.
AGDQ this year was in Pittsburgh so I got to attend a couple days. It is by far the most inclusive crowd I've been in locally, where people can just let their true colors out without constant fear. I think it's the only crowd where I've heard "trans rights" exclaimed and met with cheers. And it's truly inclusive in both directions. I'm a big old bearded straight cis white guy and nothing made me feel out of place either.
Between gaming communities and FOSS/linux communities, I think it's we nerds who are so inclusive!
