...saying Trump's like Hitler because of Trump's ban all Muslims policy still strikes me as a bit silly.
Trump is comparable to Hitler because of his general character not because of one thing in particular that he may say.
For example, when praising Putin it was brought up that he may have killed journalists who were critical of him. Trump responded by saying, "He’s running his country, and at least he’s a leader, unlike what we have on this country. I think our country does plenty of killing also, Joe, so you know."
Get a hint.
