Fun fact: The comparison isn't even completely inaccurate, Hitler's fundamental ideology (social darwinism) is also at the core of Trumps thoughts, see this long article.
It's like the fascists wanted a new Hitler but went to the cheapest Chinese factory they could find and failed to specify most of the parameters (as I understand it, Chinese manufacturers are pretty good at following specifications, but anything you don't specify might as well be randomized).
And then, when they sent an early sample to show that they're about 33% of the way there, they just cancelled the rest and went with that sample.
The funny/sad part is, the actual Hitler was a beta version of that same process.
The guy was a fucking mess. He had gas that could clear a ballroom. Was addicted to every substance available, had incestuous and pedophilic tendencies, and thought that a fedora and dog whip made him look cool.
Remove the bit about the whip and you could be describing Trump (though the addiction part might not apply to him and I don't know if Trump's reported stench is coming from gas).
The whip thing was him reminding people he was literally fighting socialists in street fights, so unfortunately it did resonate with his base. Like Punisher tattoos and rebel flags, they like cringe shit.
Probably closer to 8.0 at this point. From Chang Kai Shek to Augusta Pinochet to Idi Amin to Bong Bong Marcos, we've been minting new fascists practically every decade.
Hitler cited Southern Jim Crow laws as the model for Germany to follow in Mein Kampf.
Trump is just an accurate reflection of the worst section of our country and their legacy of evil.
The south wrote a massive advantage into the constitution by way of the electoral college, and until it's repealed they will continue to elect the most evil possible choice in any election.
