I marvel at the apparent certitude with which you introspect. Maybe doubt is supposed to be implicit in all such statements, but I'd throw some extra weaseling in sometimes to make it clearer. In any event, your analogy is horrible: "friends" means private, different reputation issues, etc.

Edit: I should add, my point has nothing to do with "abrasive" social norm violations, as I understand that term. I consider that typical LessWrongian self-congratulation.
