Without over accusatory tones.. isn't that just a giant straw man? It's a good read, and I think gets to important qualities, I use map in python but never (ok hardly ever) construct function chains, and I'm constantly reminded how imperative my code can be, and also that you can do a lot of imperative coding in Haskell.

Recursion is great when it works.

I think it's true that theorising about your atoms, axioms and behaviours and coding from them is a good goal but I do tend to think it's the rewrite we do after exploring the space a lot more linearly, subjectively.
