Why is it OK to criticize OOP using non-pure OO languages like Java, C#, or C++? Pure functional nut cases like Don Stewart and Simon Payton-Jones (whose favorite pet example of a dangerous side effect is a nuclear holocaust) don't have to defend FP from critics whose only experience with FP comes from non-pure functional languages like Python, JavaScript, and now Java and C++. Yet here we are again, with another under-informed, overly-prominent person publicly airing his grievances with Java as if all OO languages bear some collective guilt for them.

Smalltalk is not a hard language to learn. Haskell is far, far more complicated. You can download Squeak/Pharo/whatever and learn the language in a few hours. Why in 2012 is Java still such a potent argument against the entire paradigm of OOP, both class-based and prototype-based? Why does OOP alone have to put up with this sort of scurrilous, intellectually lazy and dishonest propaganda against it?
