I have been critical of the "all or nothing" mentality surrounding Donald Trump, but unfortunately this infection has spread to many other parts of our social and cultural discourse. Over and over again, too many people have to be "all in" on one side or another of a cultural issue, even when it is uncalled for. Much of this is driven by political tribalism, which has replaced principle. We see this clearly in the absolutely unhinged arguments surrounding Simone Biles' performance at the Olympics last month.
