In my mind, I don't actually conflate BLM with violent riots. In my own personal group of acquaintances, I know about two people who are real gung-ho 'BLM members', and they both attend Ivy League schools.
I think that publicizing the violent riots and ignoring the peaceful protests is the same kind of thing that union-busters used to do back during the 20s. They get a small group of protestors to do something unsavory and then use it to shut down all the rest of the protestors.
The 'BLM' name is probably sullied beyond repair, but their overall philosophy will get picked up by a similar group sometime soon.
