First of all, I would like to say that Donald Trump is not necessarily more evil than Joe McCarthy, who tried to convince us that our government was full of communists. He's probably not more evil than David Duke of the Klu Klux Klan. And he's not powerful enough to be compared to Hitler.
That said, he seems to be the incarnation of evil, the kind of guy who comes along like Huey Long or Col. Sanders and others whose basic appeal revolves around hatred of people that don't look like us.
He wants to build a wall between our country and Mexico. This is the case although there's been a net out migration back to Mexico over the last couple of years. He wants to ban Muslims from entering the United States, despite the fact that 11,000 Americans were killed by guns, fired by other Americans, a much larger amount than the 45 people killed since 9/11 because of terrorism.
Trump was born with a silver spoon in his mouth. His daddy had a lot of money and he passed it on to his son. He's not the kind of American who comes from poverty and builds something great. He isn't the kind of guy who has shown great compassion for people. Most everything he says is about him.
He hates Latinos. He hates Muslims. Donald Trump, in short, is someone supported by people full of hate and fear. You'll never see him in a soup kitchen ladling food to the disenfranchised.
He is a sociopath, who by definition cares only for Trump. If in the process he injures the American way of life, he'd probably say, "well the media didn't have to cover me."
