> Alt-righters (the real ones) can use the Principle of Charity as cover, cherry-picking their talking points to just barely stay within the realm of acceptable "classical-liberal" discourse, while subtly nudging in the direction of ethnostates, distributed violence against The Other, etc.

I've actually seen people try to do this, and it never works. Imagine, if you will, a closet tankie trying to nudge "classical liberal" discourse towards praise of Stalin, Mao etc. They'll never get around to revealing their "power level" because the whole worldview is just too silly from an open and "broadly charitable" PoV. It's only a few worldviews that can hope to subvert that framework, and ironically enough authoritarian "wokeness" seems to be one of them.
