Trump has presented himself as a racist continually since the Central Park 5 and especially since getting into politics. I have to take his presentation at face value and believe his words and actions represent who he really is.
Racist people do racist things. Even people that are not racist do racist things, with the difference being the non-racist realizes the error of their ways and makes changes or at least apologizes. Trump doubles down when called out for his racism.
He presents it and I believe him 100%.
