What is Zionut?
1.
Any person, Jewish or otherwise, whose support for the state of Israel reaches levels of extreme irrationality and potential insanity. Believes any action of any kind undertaken by Israel is politically and morally correct, regardless of objective evidence to the contrary, and believes any criticism of Israel, however mild or justified, to be motivated by anti-semitism (or self-loathing when made by anyone Jewish).
'John thinks Israel is right to take the Palestinan's land - he's such a zionut.'
