What's the problem here, exactly?

Visas are granted as an extension of this country's good will, and if you violate that good will the visa is revoked. Is your issue that you don't believe the conduct to be worthy of revoking the visa? Honestly, it's a little irritating that people think it's normal for these visas to be so liberally granted in the first place. That's probably why we're in this situation at all.

The Visa isn’t being denied for a crime. It’s targeting specific speech of protestors and that should be unconstitutional. Anti-BDS laws fall in the same category and those impact US citizens. You can refuse to hire based on beliefs but the government has no right to tell you what to say. If you commit a crime or materially support terrorism you have a day in court.

Not following. These visas are at the pleasure of the government. The argument you're making is that once these visas are granted we are conferring the same rights as those of citizens, which is not true. If someone gets a student visa and comes here, to go to Columbia or NYU or Stanford or wherever, and all they do is agitate protests and cause trouble it seems reasonable that this visa should be revoked, yes? They are not studying, they are doing foreign activism. That's all well and good, but student visas are supposed to be for people who want to be ... students.

And where in the Constitution do we find this notion of "rights of citizens". The Constitution governs how the federal government is allowed to act and the powers it has been given (by the states and people).

Seems unrelated to my point. A visa is a privilege that can be revoked for bad or antisocial behavior. It would be very problematic if that were not the case.
