`  Yes Ritchie we are here to write an encyclopedia and not yell at each other. That is why when a user makes personal attacks against other users we block them, so that we can write an encyclopedia and not yell at each other. When a user is blocked for personal attacks and insisting they have done nothing wrong then unblocking them validates the idea that they did nothing wrong. If the civility policy is not enforced then those who like yelling will drive off those who prefer to work collaboratively.  I don't think people are angry, just annoyed.  `
