If I said, in the US, "Peter Thiel is a woman-hating monster and the country would be better if he and every politician on his payroll was swinging from a lamppost Mussolini style" it would be difficult to make any case that I was doing anything not covered by first amendment protections.

If I'm a visitor to the country and say the same thing having signed an affirmation that I'm not going to advocate for violent overthrow of the US government it's not a first amendment case, it's a lying-on-immigration-forms case and out I do.
