Okay, so, Khalil Mahmoud.
Putting aside, for the moment, the specifics of the Israel/Palestine/Gaza issue, which is a lot to put aside...
And put aside as well the question of whether Green Card holders have First Amendment rights. It seems pretty clear to me that they do, and most reputable attorneys would agree, but never mind that.
The thing about this arrest and the serious attempt to deport Khalil is that it rests on the premise that publicly disagreeing with the government is itself grounds for legal punishment, even in the absence of an actual crime. Twitter randos are the only ones making any criminal accusations. The Departments of State and Justice are not.
Conservatives should be very wary of giving the government that kind of power. Do the last five years―COVID, January 6―really leave any doubt that Democrats would also use this kind of power to crush their enemies? Think ahead five minutes, please.
On a related note, Columbia University is continuing its record of being an absolute quisling. What do they have left to sell?
