Yeah this seems an issue in the anglosphere, but similar issues are arising in Spanish though. There's also push to change the language in weird ways from the left, although it's true that is not as widespread.
Also, while this is all coming from the left, it's not really coming from the "mainstream left" - it's coming from a fringe of troublemakers. The mainstream left, respectful as they believe themselves to be of the "other", are just letting it happen. And they're going to continue to let it happen for a while longer, until... well, I don't want to speculate too much on what happens when the house of cards falls down, but I doubt it's going to be pretty.
(I used to be a "leftist" myself, but now consider myself apolitical. I moved out of my home country and can no longer vote, but to be honest, I don't miss it at all)
If I ever start a project where I need to implement some kind of CoC, I'm going to base it on the friggin' Discordian Five Commandments and call it a day.
The problem is that my threshold for this BS has become so low that I'm basically rolling my eyes every time I see it on TV, press or anywhere else. It looks like the media is really pushing for it, be it because of profits or some conspiracy-agenda. Sometimes it causes me anger to see how people is completely distracted from very deep problems that we have to face, be my country or the whole humanity.
I even lost contact with some lefty "friends" and acquaintances because of my stances on this, which I found very sad. It made me avoid to talk about politics, which was something I talked with everyone in the past.
