1. it is important to differentiate between violence done towards individuals and damage caused to private property. i am not accusing you of conflating the two but i just feel it necessary to be explicit in these discussions because people often try to slyly discuss one as if it was the other.
2. I think a compelling argument in defense of the demonstrators in 2020, target isn't a part of the community. It pays minimum wage, makes it difficult for small business owned by the community to compete, and most importantly extracts the wealth and moves it away from the community. I am not saying there weren't better targets. I'm not saying we shouldn't (necessarily) go after government buildings if those are you grievances. I'm just saying that there is reasoning behind this even if its blunt.
(Also worth noting i read an interview with a restaurant owner near the target whos restaurant was burned down that effectivly said "yeah this really really sucks, but at the same time i understand the wider context." That's what happens when you're actually a member of the community and get caught up the fallout from these things.)
