When ICE commits violence against the unarmed grandma in the chicken suit, they radicalize ten more grandmas—and solidify the position of the normies against ICE.

And anyone who shows up to a protest is making their own risk assessment. Some protests are the strollers and marches type, and that's a pretty low risk level. Some protests are spicier, and they tend to draw a different crowd with a different risk tolerance.

And yes, I'm saying we should remain non-violent in the face of ICE's atrocities, because that is the best tactic for gaining and retaining the wide-spread support necessary to defeat them.

I think the part you're missing is what that support gets us. When there's wide-spread support for those opposing ICE, that gives us more of an ability (and the people power) to attack the pillars of support that prop up the authoritarian regime.
