While it might not make sense to Smalltalk bigots, it certainly makes sense in Smalltalk. I'm becoming more and more convinced that Smalltalk is the programming language equivalent of Newspeak.

I have observed that Smalltalk bigots convince themselves that other programmers do not understand Smalltalk when, in fact, Smalltalk bigots simply can no longer understand general programming terminology.

As they say: "Ignorance is bliss."
