During the Summer of Love, I went to one of the local protests to see what it was all about. A number of people there for the protest were genuine, and naively there in good faith: they truly believed they were protesting against excessive police force that undervalued black lives. Antifa showed up too, and deliberately took advantage of the genuine protestors, using them as meat shields, as they agitated things and turned the protest into a riot.
I managed to escape the crowd and get the fuck out of there before the protest completely turned into a riot, but on my way home, the evil of what I had seen stuck with me. I could not escape a line of thought: that antifa was going to successfully bait the police into responding with force, and antifa would make sure said police response killed someone innocent.
That didn't happen, fortunately, but for the next two weeks, "Four Dead in Ohio" was on my playlist, a lot. Those were a depressing and anxious two weeks.
