That’s not true. Your argument is the same as yelling fire in a theater, and no one ever yells fire in a theater. These rare if not none existent incidences are used to curb first amendment rights of everyone. That’s why we have no free speech zones.

Another one I love to hear is “it’s on private property so it’s ok.” you can’t break federal law just because it’s on private property. You can’t deal drugs or human traffic or kill someone just because it’s on private property, but somehow you can curb free speech. But keep thinking what you think. You will totalitarianism in no time.
