Unfortunately even if you naturalize, they're now floating the concept of denaturalization for people opposed to the regime. It is wise if you are or were a legal immigrant (or have family members who are), to keep your head down.
Everyone is making the comparison to China but when I see comments like this, I think of countries like Russia where street interviews of the average citizen invariably result in answers like "I'm not political" and "I have no opinion"
Suggesting that the most legally vulnerable group be careful isn't wrong, it is the reality for which they find themselves.
66%~ of the US either voted for this, or were indifferent about it, and are a group which cannot be deported/denaturalized. Perhaps that group should step up instead of the <1% who are most at risk from legal administrative threats.
I think it quite telling hearing born-Americans asking green card and naturalized citizens to be their "resistance" for decisions they themselves made. Reads like looking for cannon fodder, who can just be trivially deported/denaturalized while the immune citizenship sits back and points at how bad things are.
The group of people who voted for this needs to stand up against it and I don't see that happening because it requires admitting you were wrong and got conned and people would rather die than do that.
FWIW, I am not American and I don't live in the US. But yes, you are right of course. For some part of this group. But there are also many immigrants who can afford to speak up, because they are not necessarily refugees who would get deported back to a warzone or similar.
In the end though, the targeted and vulnerable group need to stand up for themselves, others won't do it. I know it sucks, but it's the reality unfortunately. And yes, others from more comfortable groups should also make a stand (and some people are), but history shows that not many will.
