I've been in professional workplaces for about 25 years now. Early in my career, I was even in a few offices where I was the only male. You'd be surprised how raunchy office conversation can get when a mostly female office forgets you're there. I've also worked in nearly all male environments and it was similar. IMHO it's not nearly as bad today, people are just more sensitive from my own experience.

The problem is the inability to stay calm and interact with people of differing views.

edit: I find it interesting, I started working in the early 90's at a time when a lot of office environments were shifting mindsets. When smoking/drinking at work was starting to become widely unacceptable, when social interactions between men and women were starting to be widely discouraged. I think a lot of things are better, and a lot of things are worse. But it was never as "professional" as some people seem to think.

I think one of the major issues, is that if I say "I'm just not into identity politics" the person will be knocking at HR's door in precisely 5 seconds and HR will be scheduling re-education for later in that day.

You cannot just be here to do work these days. You have to be an activist who happens to do work for about an hour per week, but the rest of your day better be spent expressing the approved opinions, genuflecting at the correct people, and consuming the designed propaganda. These companies don't have employees, they have activists who they are too afraid to fire.
