We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Haidt can gasbag all he wants, but this is happening because it's the intended result of a 3 generations long left wing, neo-Marxist (Frankfurt School) effort to radicalize the western population and conduct a "long march through the institutions." The march was started partially by the followers of Antonio Gramsci and Herbert Marcuse; it was underwritten by the Soviets and other left wing governments and 'civil society' groups. (Lookin' at you, National Lawyer's Guild...)
Haidt's cutesy talk about "intersectionality" does this and that made me fume. Intersectionality is just a method of imputing victimhood to various classes, then encouraging them to lord it over everybody else, in a very conscious attempt to crush western social norms. Most of the followers are dupes. The leaders are not. A good example outside of intersectionality is the NY Times' recent attempts to norm pedo behavior. Nothing to see here, kids... just a Gramscian assault on social norms, morality and the 'squares.'
It's well and good to talk about symptoms and how we can treat those but until the philosophical leftist rot that drives this revolutionary movement is pulled out root and branch from our institutions, it won't be stopped.

Richard Fernandez has also talked about zombie Soviet memetic warfare being a causal factor. Neither he nor Eric Raymond are wrong.
