MRN reader Karen writes, “Trump is a correction, a part of our awakening. Not to worry. All is well.” Well that’s a load off my mind! But, seriously, Karen may have a point. I mean, I’m not as sanguine as she is; I think it will be awhile before the phrase “All is well” springs to mind every time I see Trump’s florid visage on TV. Still, it’s true that Trump is forcing us to reckon with things we should have reckoned with long ago. In particular, he’s helped make “tribalism” a buzzword, and I think pondering tribalism is a good thing, as long as we’re clear on what tribalism does and doesn’t mean.
