Is real life political propaganda in in-game channels against the rules?

That’s extremely inconvinient, I agree. You can’t even peacefully protest him to death like all those SJW righteous fighters struggling for everybody’s greater good. Except, of course, good of that one unlucky dude who dared to say something aren’t aligning well with their almost religious radical believes. But he deserved it anyway, for being so evil and probably even a nazi.
