I always hear this sentiment that the far right is a reaction to "SJWs" but I don't think it makes any sort of sense. Is the idea that there wasn't a "far right" before SJWs were a thing. More to the point, there were waves of racial terror periodically throughout US history in response to efforts to guarantee basic civil rights. But I hope we can look back and see those phenomena for what they were. Why are we so sure that this time is different?
