Isn't sexism like anything else? There are extreme cases, quite often though just speaking up resolves it.

I have a stutter and I have been in many jobs where I have been the butt of some jokes. I have been overlooked or talked over. People have played 'guess the word' when i get stuck... i could go on.

I find in the vast majority of cases a quiet word, a quick bit of education or just straight up shutting someone down makes such problems perminantly go away.

There is sexism in the tech industry, i am sure there is some racism and whatever else as well. There will always be people who intentionally or not say something that offends. Your work place experience will depend on how you react to that.

My experience of the tech industry has shown that it handles complaints well and deals with issues that arise in a positive way. I think this is what people should focus on.

I saw a documentary about a fish market where women should be good wives at home. The few women who worked there were subject to daily sexist remarks. They had a choice. Ignore it or quit... There are far worse places to work than in technology
