Tying this to politics is odd to me.
Online gaming has been toxic since day one. Anything that depersonalizes is going to be toxic and that is inherent in the online space. In the smaller communities you can actually get to know people and have some kind of reputation but as the community size grows, the consequences of bad behavior fade because nobody can remember.

The friends who all played vastly more often than I did and had all their techniques and edge jumps and recoveries and stuff practiced were furious.
Lots of "you can't do that" "that's not fair" "that's not the way you're supposed to play" etc.
edit: oh, I see your edit. Yeah, it's definitely not new.
