I've seen recent examples of the government targeting green card holders for their speech. As a naturalized citizen who wants to exercise my free speech rights, how concerned should I be about potentially having my citizenship challenged on technical grounds? Are there realistic scenarios where this could happen despite First Amendment protections?
Until recently, I would have said that the only way a citizen could have his or her citizenship taken away was by committing treason but there has been talk by the current administration about expanding the grounds as well as increasing denaturalization efforts. The first Trump administration tried this but it was largely unsuccessful but it's a different administration and a different Supreme Court so I don't think concerns now are unjustified.
Do the same people claim that arguing against Israel's interests in Gaza is treason against the US? Because I'm not sure what that makes the US government. Now imagine making this argument against a Russian immigrant criticizing Putin's regime.
