But the author has certainly picked up on the rage. Trump is no one's "last warning", he's what comes after the last warning is airily dismissed. I enjoy metaphor as much as anyone, but he is no Antichrist, nor are his followers any lumpenproletariat angry at insufficient pandering, nor are we likely to be mollified by repackaging business as usual as some sort of political moderation.
Nor is he all that likely to lose, and what comes after that isn't going to be any apocalypse, but it may seem that way to the political and cultural elites whose excesses the author has accurately described. The real difficulty is that the ground assumption on the Left has become that the duty of government is to sculpt its society and to hell with the preferences of the individual citizens therein. And that once in power it is the duty of the government, and the unassailable right of its operators, to run roughshod over those jerks from Peoria who aren't real human beings anyway.
You can think that, but you'd best not say it, is the article's bottom line. And they have said it loudly and repeatedly. And if you act on it, you've got trouble. And they have.
Great post.
