Death is the prescribed punishment for treason in this country. I did not invent that punishment, I am simply saying that these people are traitors, and we hang traitors here. Or at least, we should, according to the laws on our books.

advanced democracy like the USA, where a wide political spectrum is meant to be part of the design.

Hey - I'm all for horrible people having horrible political takes and being able to voice their awful opinions in the public marketplace of ideas. But when you storm the capital and attempt to overthrow the government, that is no longer expressing an opinion. That is being a traitor. Anybody who voted for Trump after that is aiding and abetting an enemy of the United States.

The solution is not to murder those voters but for the mainstream parties to take that stuff into consideration and make sure the far right remains “fringe”.

Yeah, well, it's a bit too late for that. The Republican party has long since embraced the cult of Trump. They've been completely hollowed out by Trumpists and there's no going back without the entire party collapsing. The sane ones in that party know this, and so despite the fact that they're terrified of Trump and his cultists, they'll still vote for everything he wants.

I understand that you see an extreme position like mine, and find it anathema to your sensitivities as someone who doesn't have to live among these people, but let me assure you: the US is a full on fascist country now. The only way to claw back any semblance of a normal country is through extreme measures. Talking it out is not going to cut it anymore.
