I follow US news a little. You seem to be much further along on your way to abolish democracy. But to be fair, the “winner takes it all” voting mechanism and resulting two party system really helps in dividing a country.
Also “hoarding weapons” seems to be an acceptable pasttime in the US.
I fear your optimism ist unwarranted. The far right is attracting more and more voters here.
The ones arrested are not the far right you see on TV. They are conspiracy nuts who want to return to the time Germany had an emperor. They planned a revolution and hoarded weapons.
Probably wanted to regain the old empire’s territory as well, especially the regions belonging to France now…
Tolerance always has a limit. And the one thing any tolerant society can never tolerate are intolerant people - because they will destroy that society. Trump and his followers are the very definition of intolerant.
Thus the “if you are tolerant, you have to tolerate me” argument is often used by aforementioned nutbags or internet trolls, and I very much hope you fall into the latter category.
And regarding stupidity - sadly there is no mechanism to ensure that it is fairly distributed. A less than ideal public school system paired with the propaganda of media conglomerates can easily result in a society with half the population considered “dumb” (not really stupid, but brainwashed / uneducated with a lack of critical thinking and/or a lack of basic scientific knowledge …) - but I would not judge the US population that quickly. Trump is probably also a symptom of the broken US democracy.
