OO should mean a lot more than that to a functional programmer.

OO gives you a fairly flexible prebuilt data-driven function dispatch mechanism. This is better than a closure with a curried first parameter because you have multiple related functions associated with the data. Furthermore you have mechanism to associate functions with data which allows you limited ability to abstract relations between things.
Plenty of Lisp programmers find this useful, which is why many Lisp systems have built-in object oriented systems. Sure, Lisp can't associate any syntactic sugar with it. But the idea of layering abstractions on top of each other so that in the end you can find a natural implementation is very well appreciated in the Lisp world, and plenty of Lisp programmers use OO.
