Looking over that link, (thank you by the way) I don't think it's strictly a matter of values dissonance. That's there, if only in how we've expanded the list of recognized options.

I think a large part of this is that Huxley didn't fully recognize details of his own culture.

Purity-culture (as we call it these days) isn't any less sex-obsessed than Fordly society as we're shown. It's just more self-hating about it.
