You can be many things on MN - adulterer, abuser, theif, Tory, and 90% people will come up with an excuse for your behaviour. But to be rude is a crime punishable by death, offenders are drowned in cat piss and fruit shoots!
MN is obsessed with manners. The only thread I started that really went nuclear (it was in chat not AIBU btw, I'm not a complete fool), gave people the opportunity to call me rude. And by golly, they did.
