Thick skins

That might be true. I'm certainly willing to argue my point, loudly (which is a behavior that I've seen LKML encourage in the past -- "we want to make sure you really believe that the thing you're proposing is correct, so we'll force you to argue it"). In any case, I'm reasonably unlikely to be personally hurt or offended, and there should be somewhere in this skin analogy for the people who get hurt and give up.

Then again, I _have_ given up on LKML, so.
