From the Sooty Empiric.
The idea is that given that Trump et al. obviously don’t care about civility norms, you’re fruitlessly tying your hands behind your back to insist on upholding them when in dialogue with the brutes. Don’t bring a knife to a gun fight, don’t obey Queensbury rules when they’re hitting all and only below the belt, etc etc. One can see the intuition here fairly well; incivility is evidently a powerful weapon of rhetorical warfare (Trump is president!) and we shouldn’t surrender it to people who will use the power they attain by it to do very great harm to a very great many people. I think that once upon a time I would have agreed (so, vain as I am, I certainly don’t think this is an obviously wrong headed or foolish take or anything of the sort), but I’m now inclined to disagree. This post is about why I changed my mind.
