>do you really want a country with one party in the control of everything (Congress, presidency, governors...)
No, but if I have to choose one, I'm not choosing the one that believes in Satanic pedophile cults and Jewish space lasers, and that gathers neo-nazis like flies, so simple math says I have to choose the other one until my country gives me a viable option besides "lesser of two evils."
>Half of your country voted for Trump,
A popular bit of propaganda, but no, Trump never carried the mandate of half the country. In 2016, only about 56% of the voting-eligible population - already a subset of the entire population - voted. Between them, Trump and Clinton each got about 27% of the possible vote, and while Trump won the Electoral College, he lost the popular vote.
In 2020, 66.7% of eligible voters turned out to vote. Biden won with 51.8% of votes cast, against Trump's 46.8%.
>and you just hand-wave them away as "Trumpists" as if they were nutjobs who should be censored
It's common to refer to followers of a particular social, religious or political movement - particularly those associated with a cult of personality - by the name of their leader. I refer to the unique blend of populism, neo-reactionism, persecution complex and conspiracy theory that makes up Trump's politics, and that of his followers, as "Trumpism" and them as "Trumpists" in order to draw a distinction between them and the Republican and Conservative ideals they supplanted.
>Funny how no one mentions this in posts about China, North Korea, Iran, Syria or Daesh. They have just set their own rules, why should they be labeled as tyranical or authoritatian countries?
Well, for one thing, you're confusing the laws of those countries and extremist groups with the terms of service of social media platforms. Twitter isn't beheading anyone, and Facebook isn't sending anyone to concentration camps, so attempts to draw some kind of equivalence between them and totalitarian regimes don't really work.
