Outsider, how do you know what "Most of us Trump supporters" believe or don't believe? Actually, many polls have shown that of persons who describe themselves as Republicans, more than 50% still think Obama is a Muslim who wasn't born in the US. Also, most of the same believe, without evidence, that Hillary Clinton is corrupt, a murderer, and a traitor, simply because that is what the RNC and FOXNews have been telling them daily for thirty years, without evidence. People believe what they want to believe, that's called confirmation bias. It takes work to be rational, work that many peoples prefer not to do, or aren't equipped with the skills to do.
