I mean, the US government is now actively (and illegally) imprisoning/deporting Ivy League students who protested in support of Gaza, so I think "having the cultural cachet" is irrelevant at this point. They have the political power and that's what really matters.
But for a less dramatic counterexample, I'd offer something like whatever group (was it Moms For Liberty?) that orchestrated book bans in libraries nationwide.
The part of this you should be worried about is that they've realized they now have enough hard power to use violence against ideological enemies instead of rhetoric.
They're being completely open that they plan to extend this treatment to native born U.S. citizens too [1].
