Crocker's Rules didn't give you the right to say anything offensive, but other people could say potentially offensive things to you , and it was your responsibility not to be offended. This was surprisingly hard to explain to people; many people would read the careful explanation and hear, "Crocker's Rules mean you can say offensive things to other people."
If you declare Crocker's Rules, other people don't need to worry about being tactful to you.:; ( You still need to worry about being tactful to them Crocker's Rules only work one way.)eliezer yudkowsky
