Nothing is hyperbole with Trump. "He hasn't done that yet" is the refrain from every Trump-apologist right up until he does the thing. This cycle has happened dozens of times.
To argue that someone should stop doing something implies that they already are doing that.
So your gripe is that my theoretical argument could be happening in the future, or that you have to change "citizen" to "legal resident", or that you have to change "stop" to "don't", or that you have to substitute it for any of literally dozens of abhorrent Trump policies? And that's why my point is invalid? Trump has openly stated that he wants to send American citizens to El Salvadorian prison camps, and I'm being completely unreasonable in imagining arguing against that?
