I don't think half the population drafted this policy, so I could easily think the specific construction of the policy is insane without believing half the country is.
I do think a lot of the details are bad. But Trump is not exactly a details guy. And while I think they could have been better (by a lot, fairly easily), I do think they are an accurate, if crude, representation of the policy vision Trump has been consistently articulating for decades (he's been talking about tariffs and trade deficits like this since the 90s).
