If a joke criticizes the left in any way, in typical Communist fashion, it's banned. This is literally the same thing as Xi banning jokes about him looking like Winnie the Pooh. Of course he's the dictator of a country, not a company, but don't think for a moment that this won't spill over into public policy. Give it a few years, and when Democrats have a one-party state they'll repeal every amendment in the bill of rights — or just ignore them, if they control the whole government, who's to stop them? Not like the Republicans wouldn't do the same thing, but the Democrats are in a better position to do it.
