One of the reasons I've long been very anti-politics/issues/activism (from anyone about anything) on games is that it isn't the purpose of the game, and it can create an environment that makes the game less effective as the kind of game it is.
A lot of people come to these games to engage in a story that is not about their real life, even if we sometimes chat about our real lives in the 'living room' of that space. It's IDEALLY not a social space where we briefly and rarely play make believe in between talking about our real lives and feelings; that's a flip of the intent, being 'this is a place to tell stories together that aren't about the real world or the real us, even if we should feel comfortable chatting socially in downtime without fear of being treated poorly based on who we are'.
The more a game becomes about the socializing living room (OOC room/channels/etc.), the less it becomes a game, and the less effective it is as a 'break' from dealing with that real life reality/a form of escapism/etc.
Don't get me wrong here; I think the 'living room' is very important to the health of a game. Part of that, though, is how much focus it has as compared to the story and RP going on.
For instance, if I go to a game and everyone is just arguing identity politics all the time (which still happens even if everyone is mostly on the same damn page about them in that group, gods fucking help us), I'm not getting to play that game, and I'm not getting something I can't get here on MSB or literally anywhere else on the internet.
That game is giving me absolutely nothing I can't get everywhere else, and I have no reason to be there.
This stuff will take over if you let it, and that's the end result (after the inevitable flame wars and arguments and hurt feelings, none of which are good, either). It may be a lovely, wonderful, amazing social circle full of people you absolutely adore! ...but it's not a game any more, and people trying to run a game need to be conscious of this.
