Sadly it looks like you have to deal with him every day...
Repeatedly stating that "Trump= hitler" (sic) doesn't clarify what you meant by saying it in the first place. Trump isn't Hitler. Although the Drumpf family (Trump's paternal grandfather) was German, the Hitler family was not. Also Trump is 71 years old and Hitler is dead, but would be 129 years old if he wasn't. Trump is over six feet tall, Hitler was five foot eight. And of course if Trump was Hitler he'd be ineligible to be President of the United States through not being born in the USA and also having been a member of the Nazi Party of Germany from 1933-1945. Trump isn't, by any measure, Hitler.
In one of your later posts you state that he's "the second coming of hitler" (sic), and I'm sorry to break it to you but reincarnation isn't a thing. Nor are past lives. So that's not true either.
Which leaves us right back at "What?". You haven't explained what you mean by equating the two people. Just stated it over and over again.
There's not much evidence Hitler loved Mercedes, although he certainly had a few, with the car we featured a few months back on Wednesday Want as an excellent example. It was the sort of car that enabled his love of ceremony, pomp and celebrity. He did very much love Volkswagen though, as a brand that fitted in to his "by the people for the people" philosophy. His whole style of leadership centered on these things - encouraging the German people to work for each other for their own collective betterment without greed, while worshipping the ruling elite (him). The Volkswagen Beetle was, initially, Hitler's ideal car: personal mobility, affordable to all. The rampant nationalism and xenophobia was simply a tool to those ends - his popularity was down to the fact that he put "true" Germans first, and put the blame for all of the really quite awful conditions between the wars (including devastating hyperinflation) on outsiders. This was commonly foreigners and immigrants, but Jews were a heavy focus almost from the start, along with gypsies, homosexuals, the disabled - anyone outside the norm of "true" Germans.
For the Austrian-born Hitler, Mercedes, as a German car company, was something to be cherished and heralded. So, no, Hitler wouldn't ban Mercedes. But he would if it were a foreign car company that he believed was outcompeting German ones, in order to protect his Germany for Germans ideals.
For US-born Trump, Mercedes is a foreign car company. Indeed he's not cherishing or heralding them as Hitler may have done. In fact he's reportedly demonising them for remarkably similar reasons - it's a foreign car company that, it's reckoned, he believes is unfairly outcompeting good old American car companies and should be taxed to the point of unattractiveness in order to put American jobs first. That's nationalism and protectionism for you - although Trump's is far more capitalist/conservative in nature than Hitler's more socialist (perhaps centrist) fiscal stance.
Perhaps work on your communication skills and learn how to express what's in your head before you start blaming others for having no idea what you mean when you just batter out single line gems like "Trump= hitler." (sic), which doesn't even have all of the required grammar despite only containing two words...
In case you're in any doubt, it's still bewilderingly unclear what you even mean by anything you've said so far. Unless you think that anyone who expresses nationalist and protectionist tendencies is somehow German, or all Germans are/were Nazis - but that would be a horrifyingly shallow position for any human being to hold.
Incidentally, you've also not clarified your "fake news" comment either. What's fake and where?
