This shouldn't be controversial, it's just common sense. Even if you're pro-Palestine, you shouldn't support violence as that just discredits your point. I know if I was pro-Palestine I'd be more than annoyed about the violence happening as I am by some on the pro-Israel side.
Exactly. That has always been the case on such issues. Just like the rioters and loothers acting in the name of BLM, just harming the cause of ending police violence.
I always used to say violence is only used by those that have lost compelling arguments in a debate or who simply want to distract from the actual issue.
