They say, ‘It’s not so bad’ or ‘You’re seeing things’ or ‘You’re an alarmist.’

"And you are an alarmist. You are saying that this must lead to this, and you can’t prove it. These are the beginnings, yes; but how do you know for sure when you don’t know the end, and how do you know, or even surmise, the end? On the one hand, your enemies, the law, the regime, the Party, intimidate you. On the other, your colleagues pooh-pooh you as pessimistic or even neurotic"

[...]

""But the one great shocking occasion, when tens or hundreds or thousands will join with you, never comes. That’s the difficulty. If the last and worst act of the whole regime had come immediately after the first and smallest, thousands, yes, millions would have been sufficiently shocked—if, let us say, the gassing of the Jews in ’43 had come immediately after the ‘German Firm’ stickers on the windows of non-Jewish shops in ’33. But of course this isn’t the way it happens.|

Read the government's court filings. They're saying they can declare that someone is an enemy alien, provide minimal notice and opportunity for due process (12 hours, and that's only after the Supreme Court made them give any notice at all) and then send that person to a labor camp in El Salvador, at which point even if a court orders the government to bring them back, the government says it doesn't have to do anything. That's not hyperbole, that's their legal position.

So unless you're already represented by counsel, can understand the notice that they are providing you, and your counsel can get into court in the district where you're being held with a habeas corpus petition and get the court to rule within 12 hours, that's it, you'll be spending the rest of your life in a Salvadorean labor camp with no hope of recourse. That is literally what the government is saying.
