Looked at Shaun Maguire's twitter page and I find it appalling. Maybe I was naive about people in tech being more tolerant (as they both work with and build for diverse people).
I think there’s an argument that the pandemic era caused a lot of resentment in tech executives. They didn’t like employees having better negotiating power, resenting the pay increases and also things like support for BLM or trans rights, and stuff like RTO factored into that showing people who’s the boss. There was also a successful outreach attempt which went under the radar until Semafor published this:
I note this "tolerance" seems to only go one way. Tolerance means supporting the people I like (e.g. "diverse" people), but it never seems to mean tolerating people I don't like. True tolerance is the reverse: tolerating people whose views you find abhorrent.
