JC said not to judge others, for with what measure you judge, you will also be judged.  That is what I live by, and that is not equal with calling a spade a spade or a Nazi a Nazi. 

I'm constantly amazed at how some people think words will just do whatever they want them to.  It's logically impossible to call a spade a spade in this context without judging it.  Anyway, JC's advice was stupid, superstitious, hypocrtical and impossible to follow in any event.  But don't worry, there's always a chance he never said it anyway.
