I found that quite interesting, but I don't think it's particularly complex.
The right has embraced that fringe 10 % - the contrarian sector, and platformed their views endlessly.
Now, as the English guy says, those views get parroted by non-contrarian types who just haven't thought it through to conclusion.
As much as the right thinks the left is whackadoodle for embracing women and trans, have you heard some of the shit the intellectual refugees they're harbouring come out with? Totally insane to embrace holocaust denial and a bunch of redneck CTards.
