It's not hard to shift "anti-American" speech to mean "anti-ICE", anti-current-administration, etc.
But it should not be enforced, or the constitution became toilet paper. I think we are arriving at the latter.
If it is this tweet you are referring to, it's about _teaching_ hate, which is only a slight nuance and still a terrible point to make for a self-labeled "free speech absolutist"
> Teaching people to hate America fundamentally destroys patriotism and the desire to defend our country.
> Such teachings should be viewed as treason and those who do it imprisoned.
Which is free speech, unfortunately.
And a very difficult thing to define, and very clearly not the sort of thing that'd be enforced against, say, the current President no matter how clear the violation.
