How about those Palestine protestors having their citizenship revoked for expressing their opinion? Supporting Palestine is illegal in Europe too, of course, but they haven't revoked citizenships over it (yet).
No one has had their US citizenship revoked. Some legal permanent residents (not citizens) who have supported terrorist organizations such as Hamas might be deported depending on the outcomes of their court cases. I don't support those actions but let's be clear about what's actually happening.
Expressing their opinion? The protestors literally assaulted Jewish students. They illegally took over property. They prevented people from accessing the classes they pay for. This was an illegal riot and terroristic to any observer.
Also no one has their citizenship revoked. People who are immigrants but not yet citizens are getting booted for breaking the law in numerous ways, including supporting sanctioned terrorist groups. It goes well beyond legally protected speech, even for America.
Then I must have mixed up details from two different stories. But he's relevant anyway. Are permanent residents exempt from the first amendment, or is he being deported for something other than his speech?

Generally citizenship can only be revoked from a naturalized US citizen if the government proves some sort of fraud on their application.
