It’s because it’s All About Them. Their (as fragile as spun-sugar) ego is all-important, and anything that threatens it has to go. And since they wrap their ego up in Being a Republican, and Being a Strong White Man, and all the racist bullshit that goes with that stance, that makes Harris is a physical manifestation of everything they hate. Such ‘challenges’ to their ego cannot be allowed to exist.
