Isn't Trumps mob like Hitlers brown shirts?

And the Red Guard and the Khmer Rouge and like Jim Jones People's Temple before they drank the Kool Aid

Yes, but Hitler came back after his failed attempted coup that landed him in prison.  Trump won't be back. 

No, he was embarrassed by the way they looked "low class" - his words. They should have dressed better if they wanted pardons. 
The GOP told Romney he couldn't win without Minority votes, and Trump said, "Oh, yeah? Watch me!" and pulled a lot of racists out from under their rocks.
The reason Trump won the Electoral College in 2016 was because Paul Manafort fed campaign polling data to the Russians, then they pinpointed what obscure counties in swing states esp. Wisconsin & Michigan for Trump to hold rallies in to juice & goose the turnout. Some people might call that collusion, but hey, there's no such law on the books.
Trump's still in disbelief that he didn't have that same advantage in 2020. He never could admit that he wouldn't have won in 2016 without Putin's help, and losing 2020 reinforced that. It's hard to get rid of the name Trump but it will always be synonymous with "Sore Loser." 

No, not really. Antifa is more like that.

Yes, I would say so. 

.. I'm trying to think of a way there's any resemblance. The people harassing, intimidating and destroying the lives of people for having the 'wrong' political views, are not conservatives.. they're the increasingly disgusting left

You are living hate. DISGUSTING
