If by complete coincidence he thought these four people who all just so happened to be black women were stupid and had not earned their success (which far exceeded his own) then presumably he would have been able to provide a coherent explanation as to why they have achieved so much and far more than he had. He didn’t, did he?
Why did he even mention the fact that they were black, or query the qualification of black pilots and not white ones, or make comments about allegedly “moronic” black women working in shops if he didn’t consider the fact they were black relevant to the alleged point he was supposedly attempting to make? Why did he say that the Civil Rights Bill was a mistake?
You have demanded evidence of the things he said even though it is available to all in the public domain and posters have provided it: direct quotes, even videos of him saying these things which are unequivolcally and objectively racist.
What evidence did he provide for his assertion that these women including Michelle Obama are not intelligent and that they “took a slot from a white person”? Should he not also have had to provide evidence for his assertions, as you are demanding from others? Or is this yet another situation where different rules apply to different people depending on their genetalia, religion, sexual orientation, skin colour, etc?
In the absence of any evidence or rationale from you to support your position (and plenty to the contrary), his views are clearly exposed for precisely what they were: very clearly expressed racism, misogynism, homophobia, and general hatred of anybody who didn’t want to live in the Handmaid’s-Tale-esque vision of society that he was attempting to have imposed by force on everyone else in the US.
