I think you are trying to expand this too broadly in an attempt to deflect attention on to other groups and different arguments to be made. The point I was making was simply that the left is far from being saints when it comes to their organized extremists and they have done some chitty things. .

Everyone knows who the Bolsheviks, Stalin, Mao and Pol pot are. All of them had adherents, far, far significant in number than the Manson.

Yet, you chose the small LSD Cult the Manson family (who had a very vague political ideology), to make your point. Why?

They loved the chapter of revelation, which is basically what all mentally unstable and dangerous Christian groups since the middle ages did.

But you take that none argument way more serious than my post did. It's a childish analogy you are opening. Yes, the cult of personality is dangerous and over the top with George Floyd, but the dude is not the first nor the only person, who people blindly follow. Be it Michael Jackson, Genghis Khan, Stalin or Trump.
The way drugs were used by New Age hippies searching for meaning is way different than the drug use Floyd engaged in.

Like said before it is pretty weird to equalize the two dozen Manson family to large political movements and not to other cults. The Westboro Baptist church would be a similar small extremist right wing cult for example.

When it comes to New Age esoteric beliefs there often is a right wing/left wing crossover anyways. Hippie groups adapt white supremacist Thule society ideas, while many neo nazis(actual neo nazis not just conservatives) love that stuff as well.
