The irony is found in this fact: Those who accuse conservatives of being "judgemental" for criticizing the leftist voting habits and beliefs of RINOs are themselves passing "judgement" on the voting habits and beliefs of conservatives (e.g., "You conservatives are bad, bad, bad to do that").
This should come as no surprise, since relativism is built on contradictions, and an irrational contempt for the laws of logic.
When someone in the family suffers from 'stinking thinking', I would hope someone else would persuade me of a better way, in all intelectual honesty. And being intellectually honest is by default not required to be a RINO...
