How acceptable would "sane Trumpism" be? (not to you, but to America)

You’re ignoring competence.

Personally, I don’t care about the majority of Trump’s tweets (except the ones where he gaslights the idea of becoming President for Life) or that he’s crass.

High level policies like “Illegal immigration is illegal. Let’s actually do that.” I’m fine with. Locking kids in cages, morality aside, is stupid. A competent President wouldn’t do it as part of an anti-illegal immigration agenda, so it’s moot to talk about it being a policy point of someone more acceptable than Trump. A polite and quiet incompetent who ruins everything he touches still is still going to be hated.

At a high level, Trumps policies are fine. Many of them are, in essence, the same policy that Obama had: Taking on China, reducing illegal immigration, etc. Trump’s version stands out not because it’s evil so much as that it’s undertaken in moronic fashion that does more harm than good. That these measures also contain evil is just icing on the cake.
