How about going and breaking the windows of one of the establishments that you're angry against instead of fucking up innocent people's property? It is irrational to break the property of people who have nothing to do with what you're angry with. This doesn't suddenly change depending on the situation. It has nothing to do with race. That's irrational behavior for any human being. Breaking a window of a deli doesn't suddenly become a rational action just because you're angry with police brutality. And I don't think criminal activity should be ignored, regardless of why it was done.
Again, the property damage is the result of a systemic view. It's about anger at the system as a whole. I mean, they could go and smash all the windows at police stations, court houses, and legislatures, but I somehow don't think that'd be possible. I don't want to generalize too broadly, but even owning a deli shop is an unlikely dream for many African-Americans who either won't have the capital or the credit to get a business loan, nor have generational wealth to depend on, because the social system
as a whole limits the ability for African-Americans to get and keep wealth. Employer discrimination, high arrest and ticketing rates, and a weak welfare system all of which followed decades of violence, labour appropriation, moral degradation, and enforced poverty.
I'm not saying property destruction during protests is a moral good, but rather that criticizing victims of extended social injustice for being upset at the society which wronged them is a symptom
of ongoing repressive rule.
