Polling from them says about half of Americans have an unfavorable view of ICE, a far better rating than Congress, for example at 80% disapprove.

So you’ve got a swath of people who are fine with what ICE is doing, or don’t care to even make their dissatisfaction known via a survey, much less the ballot box or via a riot.

You said "Don’t forget half the population (within polling MOE) supports this, believing ICE/ removal operations are making America safer...".

That's not true. Barely a third of Americans believe that. Nearly half of Americans want ICE outright abolished.

Ok, so revised: half the population wants ICE abolished and nearly half the population has a favorable view of ICE.

The OP question was why aren’t Americans rising up and resisting ICE, and the answer I gave was because about half the population doesn’t even dislike them enough to answer a survey negatively.

I'm not sure that revision is correct either. What poll shows half the population with a favorable view of ICE? I can't find anything that high. The highest I see from reputable pollsters is 40%, and most show it is decreasing.
