I'm a socialist/anarchist, as you've hopefully noted, and, just speaking for myself, the only reason I've commented here at all, and only on the topic of the riots, is because I have nothing new to add about the systemic injustice of police or the murder of George Floyd. That's an obviously horrible thing and I haven't seen anyone saying otherwise in a place or way that I would have something useful to say in response. (Admittedly I haven't been reading this thread very closely... way too much too fast to keep up). If anyone was, and especially if nobody else was refuting them, then I would say something. As it is though, I have nothing useful to say. But then I see people like you, who obviously have the right sentiments at heart, saying things that I have little technical disagreements about, so that's a thing there's reason for me to comment on.
I've long had a suspicion that a pattern like this is behind a lot of arguments over outrageous topics (in the literal sense, of topics that provoke outrage):
Say someone stomps a kitten's skull on video, and that provokes a bunch of (righteous) outrage, and lots of people are shouting "kitten stomping is wrong!" That's a pretty obvious truth that I think almost everybody is going to agree with, and when everyone else is already shouting it, a lot of people won't feel any need to say anything more about it themselves.
But then someone outraged about the kitten stomping does something a little over the line to express that outrage. Someone who had nothing useful to add about kitten stomping being wrong (because it obviously is, what more is there to say) might speak up about that reaction being over the line, not to defend kitten-stompers, but just as a matter of principle.
While that outrage is completely justified, and some people overreacting is understandable, it's also good that some people with more emotional distance from the situation keep level heads and watch that things don't get too out of hand. But then some people spin that level-headedness as
not being outraged enough about the kitten-stomping, and consequently as defending the kitten stompers.
That in turn provokes other people to defend the level-headed people and their right to
not be outraged, and so the conversation ends up circling around that topic, instead of the original kitten-stomping.
All because there isn't really anything to add to "kitten stomping is bad", not because anybody disagrees with that. If people
did disagree, then there would be more discussion about that, and not about overreactions to it. The only reason the conversation keeps circling around the reactions to the original offense is because everybody agrees that the original offense was wrong, but some people contend that the reactions are all perfectly justified, and conversation centers around wherever there is disagreement.
TL;DR: You defending the overreactions to the original crime is why everyone is arguing with you about that, and not talking about the original crime. Everyone agrees the original crime was wrong, so there's nothing more to say about that.
