Human beings are rationalization machines.
Here’s how that works, in 1991 when David Duke a member of the KKK ran for governor of Louisiana, his numerous voters were saying, at that time cause they interviewed lots of them for tv, that David Duke isn’t racist that it’s all the media and they would give a challenge prove that he was racist.
People rationalized that David Duke a criminal and a member of the kkk wasnt racist and voted for him.
There is no question that people right now are rationalizing that Trump isn’t racist as well. No amount of education can overcome self deception.
