At some point we have to be willing to be intellectually honest about who speaks and acts with respect and integrity and who does not.
E.g. when Trump says there were "very fine people, on both sides" of a white supremacist rally, what should we make of that? Should we quibble over implausible re-interpretations of his words and conclude that maybe he meant something other than what's obvious? Should we say hey, okay, maybe Nazism and white supremacist movements deserve another look because, like, everything's relative, man, you know?
When Trump uses racist and sexist dogwhistles (e.g. "a young woman governor") to denigrate to his political opponents, what's the takeaway there? Is that okay? Is that a man worthy of respect, of sitting in the Oval Office?
When Trump suggests that we should inject ourselves with "disinfectant" to cure COVID, am I supposed to conclude that he is so smart I just can't possibly understand the genius behind his words (it's so simple!) or should I throw that on the pile of evidence that he's an ignorant person with no capability and/or inclination for understanding complex issues?
If I thought everything was relative, I'd have to think nothing mattered more than anything else, and the logical next step would be to lay down in my bed and wait for the sweet release of death. We live in a world that is not black and white, but we have to do the best we can to be better people and hold our leaders to high standards. Intellectual honesty is the first step, and it's what the GOP and their more intellectually accomplished adherents lack.
