Nope, never hear the phrase, "Check your privilege". Never heard that "hard work" or "on time" was a dog whistle for white privilege.

The reason I say this is to point this out: Whenever someone says that you have "privilege," that you should "check your privilege," or that you are "oblivious to your privilege," or that you are "punching down," they are employing the language of critical theory, and using the "toolbox" of critical theory, to deconstruct the oppressive systems of society, and to illuminate the "invisible chains" that oppress the oppressed classes.
THAT IS A CONCEPT DERIVED DIRECTLY FROM CRITICAL RACE THEORY. THAT IS CRITICAL RACE THEORY IN ACTION.
Whenever a teacher tells your kid that he is privileged due to his skin color (or sex, or sexual preference, or able-bodiedness) that teacher IS doing Critical Race Theory. He is teaching your child Critical Race Theory. He is indoctrinating your child in Critical Race Theory concepts.
(Note again that Critical Race Theory would, by strict terminology, only apply to race, but the whole "intersectional" strain of critical race theory involves the "complex intersection" of differing but interrelating relationships of privilege and oppression -- straight-gay, white-nonwhite, male-female, cisgender-transgender, able-bodied-disabled, etc.)
It's that simple. The left keeps pretending that Critical Race Theory is only this "high-level academic concept" that only very educated people could possibly fathom.
Bullshit; it's simple-ass pile of stupid nonsense that idiots can master in days, which is why it's so fantastically popular among the stupid and academically ungifted.
The stupid do not go ga-ga for very difficult subjects like high-level math or physics. You do not start a cult for the weak-minded by making would-be cultists write out Honors Calculus proofs.
No, you attract the stupid and smoothbrained with soft, gauzy, easily-concepted bullshit with five or six main rules you can grasp in about an hour and a half, tops. Stuff that makes you feel like you've really learned the shit out of something when in fact you've really done the intellectual equivalent of reading the back of a cereal box.
The Sokal Squared hoax trio had to do some reading in the fields of Critical Grievance Studies to hoax multiple Grievance Journals into running hoax papers, but, get this, they only had to do a couple of weeks' work to become experts in the field capable of producing not only journal-worthy work but award-winning journal-worthy work.
Yeah they're bright people with academic training in other fields but if you can fake up an expert-level mastery of a field in a couple of weeks it's not a rigorous field, is it?
This is not a field with rigorous merit-based barriers to entry. This is a field that is intended to validate the egos of those who feel insecure and left-behind, not to challenge them with difficult subject matter that will only make them feel worse about their limited intellectual capacities.
And furthermore, there is part of a field the academics call praxis, the practice of a theory, the implementation of a theory into action; in stupid critical theory terms, categorizing children into groups according to their "privilege" or "marginalization" is the praxis of critical theory. That is critical theory in action.
Academic papers exploring exciting new frontiers in the expanding horizons of marginalization and "decentering" are the theoretical part of critical race theory, but telling nine year olds that that their race makes them toxic is the praxis.
That's the Applied Critical Race Theory.
