Protecting the ego is the instinctive feeling to any proposal different and important to your own. I think regardless of the intention, every message has multiple meanings; to educate, to inquire, to impose, to shift attention and importance etc
... If I was happily supporting something anti-ethical or something that would affect your feeling of worth:
1) Learn from each other (Evaluate a logic)
2) Attack each other (Defend what you value ::suppression/threat/distortion/tangent/ad-hoc etc)
are you in a position to believe that 'evaluation' will contribute? or merely promotes my agenda?
