In no order:
1 – I like Kevin Williamson, a lot. One of the things I listen to is Mad Dogs and Englishmen, his podcast with Charles Cooke. Who is also an NR writer.
Along with Douthat, I don’t think there is a brainier, more reflective set of political pundits out there. The rest of the field, conservative and liberal, pales in comparison. With them it’s an advanced discussion of politics analyzed quite expertly against classical philosophy and literature.
Ezra Klein and MattY argue this stuff with a much more awkward grasp, when they do. Josh M is a one trick pony, he’s a snark merchant. Chait is smart, has written smart things, but has been overcome by the urge to be a sardonic quote. He’s also a mere Obama sycophant these days.
So I do see Chait’s critique here as weak, drive by snarking.
2 – Williamson isn’t a racist. All you have to do to observe that is read and listen to his stuff.
3 – I dunno, monkey allusion has the makings of a racial allusion, but see item 2. One thing is, Williamson is both a wordsmith and recalcitrant. If he wanted to describe something using primate adjectives, he wouldn’t be cowed out of it because other connotations.
