The "Coddling of the American Mind" guy? Pass. I was in college during the period he wrote about, and my impression is that he agglomerates mountains of misrepresented evidence to work the older generations into another panic about kids these days.
Do you have any support that he misrepresents mountains of evidence? Did you dig into the mountain and find a bunch of places where he misrepresented data? Or did you just go with your gut?
When I hear statements like this, I usually take it to mean "I don't like the conclusions he is drawing with the evidence"
In addition to what 'EMIRELADERO linked - like I said, I lived through the exact period in the American university system that Haidt reported on, and his descriptions don't match my first-hand experiences nor do they match the experiences of my peers. As a result, I do not consider him a trustworthy source. I'm not going with my gut, I'm going with my eyes and ears.
