I don't think any other president promoted anything like January 6, and doesn't recognize an election of a president to this day - undermining democracy, the same democratic system that elected him twice.

Just that alone is enough I think.

But you can also see his disgust to western democracies, and his fascination with autocracies, the vast majority of them are extremely incompetent - thank God for that at least.

What about the Russian Hoax to discredit Trump's first presidency?

What about the repeated attempts by left wing fanatics and the rhetoric that supports such actions, like claims of being a king or a fascist?
