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.
Oh yeah, there are attempts all over the world, but for some reason it seems to "stick" better in the anglosphere.
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)
The really interesting thing about all this CoC nonsense is how it's making strange bedfellows between some on the right and the left who have a keen interest in civil liberties. I'm a lifelong social democrat and have a lot of issues with barely-regulated free markets, but holy hell am I ever sick and tired of this identity-politics BS. I just want poor people to have free healthcare and educational opportunities, man. I didn't sign up for this personal-pronoun-crusade crap.
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.
I'm basically in that place. I'm also a social democrat, yet I'm seen myself distanced from the left, be it parties, social movements and so on, as they seem to embrace this more and more. I also studied sociology so I can spot the BS from miles ahead, even from people who pretends to be thoughtful and so on.
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.
