I know what you're trying to say in this thread spud. I'd like to add that I think that judgement serves many purposes, from self-preservation to aligning oneself with the herd, etc. Most people don't even think about why they're judging, they'll just listen to someone else.
As far as dietary choices go, all that I can say is that I choose my diet based on what will nourish ME the best. Compassion begins with being compassionate with myself.
