If that is all it takes to piss off a mod, they need to be demodded immediately. That really the weakest insult you can throw. [The insults are more annoying than offensive]
To be clear: your position is that SO needs moderators who don't downvote "cunt" because it's not offensive enough?
Anyway, doesn't matter--throwing insults, weak or strong, deserves downvotes. I don't understand why you're defending his right to be a complete asshat on a moderated forum. It's only just barely even related to the topic at hand, since he earned his downvotes.
