I've said this once and I'll say it again. The extreme left are as bad (or worse) than the extreme right. They are what created the alt-right, after all. If you're going to call white people bigoted and racist and generalize all of them like that, just for being white, of course there is going to be an opposition. Even if there wasn't one prior. It will manifest in a response.
And no. This isn't the whole of the Left. It's a small minority, but it's a very loud minority and it's done a lot of damage to our culture.
I think I might disagree with you on that. The Far Left is not as Far Communistic as the Far Right is Far Nazi. Neither is any good, but the Left is closer to the Center of traditional US politics than the Right is.
Consider the talk TV shows. MSNBC is no where near as far Left as Fox is Right (and there are worse). And the radio shows on the right are screaming crazy. The difference is that the Right yells about Hillary Clinton dealing in child sex slaves at some pizza place and the Left asks for independent investigations into Trump surrogates with business Russian connections.
There is no rational equivalency.
