It's a manifestation of cognitive dissonance. High intelligence leads to the ability to rationalize almost anything. Ideas posited in this thread threaten some people's conception of themselves and the world ("I am not racist, I treat everyone fairly, the world is a just place"). When people's identity and worldview is threatened, they try to annihilate that threat (usually not violently, but that occurs also e.g. violence against trans people). That's what is happening in the comments here - arguments about semantics without addressing the whole point of the testimony.
