The kool-aid drinkers.
I don't like Clojure or ClojureScript. They are both awful by virtue of the platform they exist on. I would like very much if Clojure had a core lisp KLambda, because I could abstract Clojure onto a platform that wasn't terrible.
Rich is a guy who (whether consciously or otherwise) hated writing Java and decided that functional programming worked, and that Lisp did too. Clojure is a strange abomination from the points of view of those in the pure-functional family, and those from the paren-dimension, but I find that Clojure code reads easily, and comes off far more expressive than that of Python or Ruby or other so-called expressive languages.
When someone who uses the JVM tells me that something I know to be true is 'fundamentally flawed' I become fearful for myself, that I might drown in irony.
