I don't think that folks are braodly supportive of ICE here, though I think that a) the folks who do support it are loud and b) most of the folks who don't support it have fairly reformist politics and are opposed, for instance, to us protesting while open-carrying.
For the record, I am highly worried that open-carrying by the counter-ICE folks at these events will be the next escalation- I carry a stop-the-bleed kit (and did some formal training). We are more worried about getting shot by counter protestors at this point.
