That's the easiest and most superficial rationalization for not bothering to try a Lisp (any Lisp), but also the least compelling argument against it, and likely not even the most significant actual reason you haven't bothered to learn it.
I was joking about the syntax and the way how I just can't wrap my brain around reading lisp and matching parentheses.
I was not joking about the recursive and functional nature of Lisp, both of which I'm finding very interesting (and my coworker is, in fact, a big fan of Haskell)
