Fair enough, though I'm not sure all of your points need reflect on the rep discussion. It's not like neg rep has never been an indispensable communication aid. If anything, it encourages lazy communication (neg rep and we're done - no explanation needed).
It's not like I care that much, though. It's just rep.
I wonder if this is really a discussion about my own sensitivity. In which case I can say: sure, I could learn to have thicker skin.
