I think the point of the argument about functional programming is that you can't defend a stance of absolute rejection of all things non-functional, because that kind of world could not exist. Similarly, an all-object world does not make sense, either.

His other point about OOP, though, that it doesn't have first-class functions -- that's equivalent to complaining that it isn't functional enough, which is not supposed to be the point of OOP, anyway. There's a lot you could criticize about OOP, but he doesn't make that strong of a case here. He's sort of treating it as a mirror image of fp, but it came from a different world with different values and it's not on the same footing.
