Understanding you perfectly well isn't the issue at point, it's the manner of how you present yourself - witness all the crap in this thread about RMS from those people who now accept that he didn't wish Jobs dead, but still say he should have been more polite about it. You don't have much of a credible leg to stand on if you don't engage in that which you request of others.

Edit: changed 'moral' to 'credible' to avoid semantic bickering about the loaded word.

Morals? I think I have been talking squarely about effective communication, not morals.
