They literally said that they will deport Haitians, who didn't do anything wrong, followed the law, and are here legally.
Just because they are in the country legally does not mean that they have permanent residency. If they have applied for asylum, we will have to see if they are granted or not. Kamala grant asylum status more easily while they will not.
That's your interpretation. Trump said he will deport Haitians, he didn't elaborate if there will be any consideration about asylum, and knowing him it wouldn't make sense to assume he'd be humane about it.
Also at some point during the first campaign or his first presidency Trump did actually claim that he could revoke some green cards. So it's not an exaggeration at all.
Yes? How many did he revoke? We already know he is a big mouth, in the same way that if he wins with a clear majority there is no way he is going to kick out 20 million.
We're discussing policies proposed by the candidates and this is one of them. I can easily say that e.g. Kamala's price gouging proposal is bullshit and disgraceful populism. Can you say the same thing about Trump's immigration bullshit, or do you still (selectively) like it?
To put it another way, if Trump says (completely hypothetically) that he would jail journalists or let police do whatever they want, would you still be "sanewashing" it as if that could never happen, even given the near-absolute immunity granted by the Supreme Court?
Not to mention just the basic fitness for office implications. How much can someone talk nonsense, including unlawful and unconstitutional nonsense, before we should say that no fucking way this person is fit to be president. Rhetorical question of course. There is longer any guardrails on at least one side of the political spectrum.
