All right, that premise was half invalidated...let me rephrase. Anti-government speech doesn't bother my legal considerations in the least. What does is the notion that not only is the government corrupt, but that it would be less so if replaced by either the Fourth Reich an absolute theocracy. That's not a Constitutional objection, just a personal one. Hell, if enough people vote for censorship, hiding statues' breasts, and airline security, it's all legal...I just may decide to stay in the military far far overseas in that case. I stopped going to bars where the Bible-thumpers yell at random passers-by because at some point I'd get drunk and lose my military career by punching someone in the gut. So they've won.
Is a court order to keep these people away from military funerals enough? And if so, why is it so difficult to enforce?
At some point we may be facing multiple cities in open rebellion and still within the "law." Look at some parts of Nevada and Utah, where some of these groups are expelling whole generations and practicing not only polygamy but mob-like violence and property takeovers.
These people are heavily armed, have no allegiance to America but instead to a central religious figure, and are borderline terrorists...they don't want a revolution, they just want the theocracy to spread until it absorbs the reasonable parts of the country. You don't need much more than free speech, religious texts, and time to do that. Is it stoppable? Maybe, but maybe not by any legal means. So then what, secession?
