You are correct, the wingers are the problem...but the problem is that the "wings" keep growing as more and more people become radicalized.
Even you admit to voting/supporting someone based upon their level of trolling the left. You do not seem to care about trolling of the right...which seems to move you closer to being a winger yourself.
I care but the Right is more overt about it. The racism, nationalism, etc. But the Left is not quite there yet. For some reason people like David Duke are vilified but people like AOC are celebrated. Odd.
And here is a major problem. Both sides clearly can go to far. To far on the right has been clearly identified and mostly, IMHO, because it is covered in outright bigotry and hatred. The left, OTOH, has not identified what is to far and, again IMHO, I think that is because they are veiled in the false pretense that they really care when it is clear that hatred drives the extreme left as well.
Jordan Peterson, no matter what you may think of the man or his public face, I think really hit the nail on the head on this particular subject. The left goes to far when it tries to veil itself in equity of outcome - a horrific concept in practice that pretends to be about caring for those less fortunate when it is actually about visceral hatred of all those that are doing well.
