There are US citizens who want to shoot gays, kill people different in creed or heritage, and bomb people for religious reasons. We had the gay panic defense (the legal defense to kill gay people just because you found out they were gay, and the shock justified you killing them). We had people shooting sikhs assuming they're muslim. We had folks bombing abortion clinics. There are US citizens who have done far more, and far worse, than writing an op-ed or taking over a building.

So, frankly, why not treat these people the same we treated like these other folk-- a trial and then appropriate punishment proven in the court of law. If an immigrant is violating the terms of their visa, the US gov't can prove it in their own courts and then deport them appropriately.

Those situations aren't comparable. While I oppose bigoted behavior by US citizens, for better or worse they have an absolute and inviolable right to remain in this country. Aliens generally have no such right. Entering and remaining in the country is a privilege. I oppose arbitrary arrests and deportations conducted without due process, but in principle there's nothing wrong with holding aliens to a different standard than citizens.

From a political standpoint, why should US citizens pay taxes to educate people who are apparently hostile to our fundamental values?

What about is always a bad answer. It comes of a defensive.

Indeed, I agree with you. There are US citizens who want to do reprehensible things, and I still say: maybe the US is not their jam. No, I'm not advocating exile or illegal detention. Just stating a fact.
