Daniel Buck, James Furey: A Language Arts curriculum widely used in U.S. schools ignores academic fundamentals in favor of radical pedagogy

There is absolutely nothing surprising about this.

Basically all the intellectually weakest parts of universities have accepted this mishmash of postmodernism and critical theory--and it would be redundant to add: radical leftist politics. 

It's everywhere. People who are not very smart, not very well educated, and not very good at philosophy have accepted this tangle of utter nonsense as if it were some sort of unquestionable foundation of all knowledge. When people say, for example, "critical race theory is not being taught in Virginia schools!", that's about as plausible as saying "there is no slant leftward anywhere in Virginia schools." Saying--as the left has basically been doing--that you can't find any part of an official curriculum titled TOP SECRET CRITICAL RACE THEORY INDOCTRINATION PROTOCOLS...well, you see where I'm going with this. You also can't find any part of the school day called "Radical Leftist Political Brainwashing Hour," either. But if schools don't slant hard left, I'd be astonished. Which isn't to say it's impossible. But I'd bet lots of money that they do. It's also possible that the pomo-critical-theory mishmash that now pervades and rules academia and all our other institutions, and that shows up in innumerable reports on K-12 curricula...just doesn't actually affect K-12 in any way. But that's not what's actually happening.
