Full disclosure: this is a straight up straw man, because I don’t want to pay for the book to find out how they actually expand on this.

Some cultures have produced vital advances; others remain dysfunctional and regressive. All cultures are now equal. Criticism and value judgments are forbidden. Yet this new dogma glosses over the fact that certain cultures and indeed subcultures . . . have produced wonders. Others have proven middling, and worse, regressive and harmful.

I wonder where they’d place various Middle Eastern/North African cultures. By that metric, they’ve created wonders and made uncountable advances for humanity. And yet, I suspect the authors somehow land on European, five eyes parties, India, and East Asian cultures as the most advanced.
