The Supreme Court literally just signed off on doing just this based off of racially profiling people. Trump has threatened to deport even some of his biggest sycophants like Elon Musk. They've been harassing people that DO have a legal basis to be in the country and finding ways to deport them anyways. Hell, they've even admitted, openly, to looking for avenues to denaturalize people so that they can be deported.

This isn't 'partisan brainrot', this is literally and explicitly what they are saying and doing.
