If you are going to make this argument (which seems more and more common because the original direct comparisons to Hitler fall flat), how does Trump match up to Hitler in the 20s and 30s?
Where is Trump's attempted coup? Where is Trump's Mein Kampf talking about living space in Eastern Europe and the greatness of Germany and his hatred of Jews? Where is Trump's paramilitary? That was all in place prior to 1930.
Hitler rose to power in a populace that wasn't just "liberal and educated" but had also been ruled by a jingoist elite since the Prussians came to power. Hitler was an ass but Wilhelm was just as bad in various ways and preceded him. The Wiemar Republic was a shaky government crushed by defeat and a broken economy. That's not America circa 2017.
What's comparable?
I don't dispute that Trump is full of hate and is self-serving and manipulative. I don't dispute he lacks tact and even a proper understanding of politics. But if you are going to pull up history, at least treat it with respect. Put it within it's context.
What scares me is if a politician did the exact thing Trump is doing but did it with more tact and with lies that were harder to point out, we'd applaud them. Play governments off of each other and play up identity politics of various kinds and lie to citizens for decades (as has been the American way) and nobody really complains, but someone comes to power who lies to your face instead of behind your back and he's Hitler? Bomb the hell out of countries and destabilize them and it is politics as usual but refuse those same countries entry and now we care?
