There are plenty of multiplayer games I adore. However, it seems like every community has these "brain dead", patronizing, or out right toxic elements that are just nasty. I'd rather debate politics than make suggestions in some gaming communities because the responses are just so ... annoying.
As an example, I once dared to suggest that a game developer implement a mode to prevent crouched status from rendering on death cams so that players that are bothered by t-bagging could avoid it (after a match where a friend rage quit because someone just kept head shotting him -- possibly with cheats -- and then t-bagging). This post got tons of hate, and like -50 upvotes on reddit because of course someone should be forced to watch someone t-bag them.
Another example on a official game forum... I made a forum post suggesting Bungie use Mastodon (or really just something else being my intent)... The response I got was some positivity but mostly just "lol nobody uses that sweetie" and other patronizing comments.
Meanwhile studios themselves often seem to be filled with developers that understand this stuff is a problem, and the lack of sportsmanship (or generally civilized attitudes) does push away players. It just doesn't make sense to me that no studio is saying "get lost" to these elements or implementing anti-toxicity features. I just want to play games with nice normal people, is that really so much to ask?
You're playing competitive games with primarily teenagers and young adults. They are always gonna be toxic and very few companies are willing to dedicate a ton of resources towards content moderation. There are big games that do, like Overwatch, so if it's a problem for you then you should either only play those games, or play games that don't attract the young toxic crowds as much.
And honestly asking for a feature to hide your delicate eyes from teabagging in an FPS is a bit much.
