I have heard numerous well-read commentariat equating Trump with Hitler and fascism. The idea of a Trump Presidency has yet to sunk in for the average intellectual. He is yet to come to terms with the fact that a buffoonish reality TV character like Trump was able to compete and win decisively, beating pollsters and pundits. Perhaps, our intellectual friend is looking for an apt analogy to explain the Trump phenomenon, and the rise of Nazi Party quickly comes to mind for it was a movement that surprised the intellectual of that era.
But Trump's similarities to Hitler are superficial at best. There is no question that white supremacists supported Trump and Trump was only too happy to let the innuendos run and deliver votes. Trump's opportunistic use of divisive issues -- Deportation of illegal immigrants, banning muslim immigration and erecting a border wall, was a well-timed ploy to garner votes. His opportunistic use of dogma highlights the key difference between Trump and Hitler.
Hitler was a committed ideologue. He developed his brand of ideology from his experience during the first world war and refined it in the tumultuous years that followed. He went to jail and suffered setbacks, but these setbacks only toughened his resolve and his ideas. On the other hand, Trump's life has shown that he is easily swayed and has no ideologies (thankfully, or else he may have been dangerous). He is a showman but not a ideologue. Trump's was a democrat before he became a republican. He rants against Chinese and Mexicans ripping off US, but uses the very same countries to manufacture his products (even those red 'Make America Great Again' caps). He calls for ending Washington corruption but has candidly spoken about paying off politicians. In short, Trump's vocal appeals were made not because he felt deeply about it, but simply because it would work on the airwaves!
Anyone who has followed Trump's life will be scratching his head to figure what exactly does Trump stand for. He is certainly not a conservative nor a liberal, neither a democrat nor a (true) republican. His lack of a committed ideology means that he will end up being rather centrist President, even though at times he may appear to fly off the pendulum. And if he's lucky, this centrist-tilt may not be a bad thing for America or the world.
