I think the feeling of helplessness is reasonable.. Maybe they see how much more they have to sacrifice a lot more to fight this tyranny of stupidity. Only when the population has lost a lot more will they get mad enough to say "well we've lost too much" (if you see how protests go big in other oppressive regimes - the famous quote is "civilization is 3 missed meals away from riots").

Maybe it's all the Nazi thuggery of ICE scaring them, that keeping quiet feels much more safer.
