I don't know that it was Stone, he just seems like exactly the kind of creep that would love Hitler. I agree 100% that they engineered that to have a specific purpose. You are not supposed to go to Hitler and/or Nazis in an argument and if you do, then you can be dismissed. So, quote Hitler, not mentioning him by name, lots of people will pick-up that you quoted Hitler, so they mention Hitler...boom, they are immediately dismissed for mentioning Hitler. 

I just know Trump is not smart enough to think of any of this stuff. He does not give a flying fig about history, probably knows practically nothing about Hitler or the Nazis, he was not even the one that came up with "Build the wall." and initially thought that little slogan was terrible. He was convinced to keep saying it when he saw it excited people. I think his first take on it was he thought it was boring. Everything is boring if you have no interest in anything excerpt yourself...that's his favorite subject.

The guy is a total vacuum. There just is nothing in there until someone puts it in there and if people cheer, he'll say it again.
