actually made a "Donald Trump" Quiz.
Trump has demonstrated prejudice against many different people. Race is a social construct so we can apply this term to almost any group of people but in particular Mexicans, Arabs, Chinese, and "Blacks." He has been sued for racist discrimination, he has said racist things in public, and he has advocated and implemented prejudicial policies as both a president and presidential candidate. Remember to be prejudicial simply means that you form opinions about someone based on some superficial trait (like what racial label you ascribe to them) before knowing any more.
He's also talked a lot about his "good breeding" and superior stock. This doesn't necessarily mean that he believes he belongs to a superior "race," but it points strongly in the direction of him believing something along those lines.
And I do believe that his hair is real, but he is also an excellent candidate for one of those hair grafting techniques advertised on TV.
