"Centrist" is an utterly meaningless term, as the only thing it implies is not one of the two major-partisan extremists. You can call me a centrist, with my views being anchored in a libertarian perspective. Back a few decades ago when the major parties' Venn diagrams overlapped a bit more, you could call people at the intersection of the parties' authoritarian policies centrists. And as for Bari Weiss, you can can call her centrist because she will do the bidding of her employer regardless of which Party's administration they are currently bribing.
"Don't anthropomorphize the lawnmower" includes not anthropomorphizing its individual parts, like the blades. Even when those blades are swapped out for new ones, re-sharpened, and put onto a different lawnmower.
Trump, while an objectively horrible person who belongs in prison for many distinct types of crime, is primarily a minstrel for people to hate on. While he is (unfortunately) a good first-pass litmus test for an individual's politics/intelligence, criticizing him is not really the same as critiquing all of the entrenched interests that installed and continue to enable him.
