The Other Side
So should we then not use judgement?
No, we should. It is the critical faculty of being; all sentient beings use their judgement, some more formally than others. To not judge is to not live; to judge is to be judged. This is an unpalatable choice for those who would rather not be judged; it is par for the course if you don't mind.
When people tell me not to judge them, I shrug. It's impossible to not judge others; one can try, however, not to be judgemental — to not ALWAYS be judging others with the intent of deciding moral truths about them.
Besides, it's amusing to see that those who don't believe in judgement are the ones who are most sensitive to the deployment of this non-existent thing.
