Yeah, this is a very important point. The best way to lose support for your cause is to destroy property of those you want support from. It's why support from BLM dropped so severely.

BLM wasn't even doing the rioting, but they did nothing to ensure those who used their cause to riot/destroy property were snuffed out. If you come to my home or buisness and destroy my shit, or stand by while others drive in with you and destroy my shit, I'm not supporting your cause.

If people's property are instead protected, and the violence/destruction is focused towards those who are oppressing them, they'd have way more support and things would get done.
