Too bad the Constitution itself bans rebellion, isn't it?
It's also illegal for people to fire cannons at US military facilities, to pass laws divorcing citizens from the protections of the Constitution, and for states to form armies and make treaties with foreign governments.
But people who refuse to accept reality are going to listen to the people making money off whatever cult it is those reality-deniers (hahahahaha) want to follow with their emotions.
We see it with the Earth Worshippers.
We see it with the Apollo-Hoaxer clowns.
We see it with the Flat Earthers and the Crop Circle weirdos.
And we see it with the Secessionist gangsters who simply can't accept what the Constitution itself says about the matter.
Unlike others, I took an oath to protect the Constitution from all enemies, foreign and domestic. So I actually read the Constitution and studied the history of the United States. Thanks to the Rodents atavistic need to own slaves, something they still pursue today, they illegally started a civil war in a disgusting effort to protect that institution, and the secessionists today, who allegedly oppose what the Rodents stand for, are repeating the same failed arguments the Rodents used 160 years ago.
Gotta ask why that is.
