Don't be defeatist. This is the shit that begins the rolling momentum that eventually causes stuff like that. Actions like you're talking about, absent obvious popular agitation, get treated like isolated random criminals, irrelevant and unsympathetic - see Luigi Mangione. And of course too much violence too quickly will result in extremely violent gov't response.

I understand feeling jaded but we need enthusiasm, support, action. The stuff you're saying is the opposite of that. But on the whole, I'm with you in the sense that I'd rather see 100 LMs than 1MM protesters. I think we're threading a tricky needle though.
