I’m all for calling out exactly how Koche, Trump, etc. policies are destructive to my view of what society should be. But hazarding a guess as to motivation is the gateway to a long, slow descent. Hatred of the “other” is the meth of any political movement (and God, it is tempting). It makes the practitioner feel good. And it rots their soul.
I’m on the older side and I’ve yet to see (in my lifetime) a positive outcome to a movement that embraces hate. Even when it is well deserved, hate is the soul-killer.
Hate is a motivating force for the intelligentsia ('sup, Marxists) and drives discussion. It is, indeed, bad for public policy, which is why those without impunity on the left come up with compromises that work. The piles of motivated cash from the rich right, dispensed over generations, have actual impunity, so history and consequences are removed from policy consideration.
Yes, motives and tendencies matter.
