In this thread the goal is to list rules which people live by, in practice, which tend to stink for everyone else.
If someone offends you in real life, go complain about it to everyone except for them.
If someone offends you on the internet, go harass and troll them until moderators intervene.
If you are an employer and one of the people who work offends you in some minor way, just fire them.
If you hear a coworker say something that would offend a manager, remember it so you can tattle when this coworker offends you.
