So you just magically assumed that he is "sick and fucked up" for no apparent reason. Oh wait. I forgot. He might be lefter leaning then you, and in your delusional psycho world, everyone lefter leaning than you is automatically lumped into "the left", which is comprised entirely of extreme-left-wing nutjobs. There is no scale. No divide. Just "the left".
How about a news flash: there is no "the left". I mean, jesus fuck, a vast majority of people who vote "democrat" are probably closer to the middle or even over on the right side of the political spectrum. The only reason they didn't vote R is because the Republicans in general have constantly shifted their stance so far Right that they can barely even see the center line and those people just don't want to go that far right..... Are there "Rabid leftists" out there? Yes. Do they represent the entirety of "the left"? See above. They are a tiny fraction of a minority on the left leaning scale.
And as for the Cov Cath kids? I'm going to go out on a limb and say that regardless of if you can or can not hear them being racist on the videos available, if someone says they were being racist little shits while at that protest, I am inclined to believe they were probably being racist little shits at the protest. I mean,
it's not like they don't have a history of being racist little shits. But of course, these are the proud and shining examples of future core Republican values being hurled under the spotlight. So of course, the right will do everything in it's power to paint them as innocent little flowers......
