It is absolutely imagination that leads Clinton supporters to compare Donald Trump to Hitler. He is a nationalist with dangerously intolerant rhetoric. I understand this and my imagination is also functioning. I am able to use deductive reasoning as well to assume what a Trump presidency will include. My reasoning tells me it will be much alike to George W. Bush’s presidency (which was surprisingly similar to Obama’s presidency).
I’m willing to grant the Trump-haters the comparison to Hitler. There are probably a lot of politicians who are more similar to Hitler than we are comfortable admitting. Many politicians likely have more in common with Hitler than they do an average person. Many are entirely self-serving, self-aggrandizing, self-interested, sociopathic, narcissistic, immoral, deceptive, unrealistic, racist, engage in nationalist rhetoric (whether they’re really nationalistic or not), and so on.
The American oligarchy is currently plundering the world and subjecting people across the globe to poverty, death, and destruction, and it has been doing this for a while. Fred Koch, the father of the notorious and villainous Koch Brothers, made his fortune building oil refineries for Stalin and Hitler. Yes, that Hitler. And that Stalin. Now, the Koch brothers, who landed in the lap of ill-gotten wealth, use that wealth to slake their own unfathomable greed and undermine democracy at the expense of you, me, and the rest of the world. How many of our politicians have they and their sordid ilk bought on both sides of the aisle? [spoiler alert: practically all of them.] How are these titans of corruption and their network of controlled politicians any better than Trump?
What your reasoning correctly anticipates, I think, is that a Trump presidency would look more like a Bush or Obama presidency than it would Nazi Germany. The reason is that America in 2016 is not the same as Germany in 1933. Not only that, but the entire world has changed in the intervening 83 years. There are many Hitler wannabes running around out there all over the world, but it’s not 1933 anymore, and they operate differently. They use different systems of control and wage different kinds of wars. They get wildly rich and powerful plying the blood-stained waters of neoliberalism and neoconservatism. They have names like Dick Cheney, J.P.Morgan Chase, and ExxonMobil.
