I will answer your question through its dual : the people who love LISP and functional programming are in my experience people who love maths - as in, algebra, etc. . You can easily recognize them, because they say weird things such as "this demonstration is so elegant !".

Functional programming of course maps (heh) very cleanly to this line of thought.

But most people hate maths and this way of thinking. In contrast, you get first year students "re-discovering" OOP ever year - for instance a common trick to make them learn design patterns is just to put a problem that calls for it in front of them, and three times out of four in my experience they will even come up with a pattern name close to the original ones.
