Are you really saying that it's harder to be a techie than LGBT in San Francisco?

I can't speak to San Francisco, but in Seattle at least, I never saw any flyers or graffiti telling LGBT people they were unwelcome and should leave town, nor did I ever encounter political discourse that LGBT people were somehow ruining the city, or scapegoating the LGBT community for local issues. So in my personal experience as an LGBT software engineer, I wouldn't be surprised if San Francisco was the same way.

I bike by "Go Home Tech Bro" stickers on stop signs pretty frequently in Seattle

Me too, and in 2014 someone tried to burn down Neighbors with hundreds of people inside, and before the pandemic gay couples reported being harassed and assaulted for walking down the street in Capitol Hill, and I heard more than one guy entering different bars (again, in Capitol Hill) cautiously check that this bar didn't have GAY PEOPLE, right? So I think the idea that tech people are less welcome than gay people is a horrendously uninformed one.

When I lived in SF it was socially acceptable to openly degrade tech workers. Nancy Pelosi's daughter went on TV and called SF tech workers "vermin" and "invaders" and described the presence of tech works as an "infestation". Open hostility and dehumanization is condoned. In no way did I feel oppressed, but it did come off as tone deaf the way people on one breath say stuff like that and in the next complain about how tech workers weren't invested in the community.

Yeah it's so tough being a tech worker. I feel almost as oppressed as the billionaires.

Who said anything about oppression? I just don't think anyone wants to live and work in a place where they are unwelcome and unwanted.

The post you're replying to literally says "in no way did I feel oppressed"

Victimization narratives are intoxicating. A lack of diversity in experiences will lead some down narrow paths.

In principle I agree with you--this is one of the biggest pathologies of our time.
