Utter nonsense.
The "rules" are that people who have signed onto the agreement will treat each other according to the agreement. We are hardly "above" those rules, we are bound by them because we entered into them voluntarily.
But by the same token, we are under no obligation to listen to whining from non-signers about whether you think we're following the agreement well enough for your tastes. You chose not to participate, so you don't get to play "agreement cop". It doesn't concern you.
It's like a signed contract between Company A and company B. You don't get to run in off the street and start accusing either company of not meeting its contractual obligations or nitpicking the language of the contract. If either company has an issue, *they* can raise it with the other company or take it to arbitration. But if you try to butt in, you're just being a meddling busybody.
That's not being a "second class citizen". But if that somehow makes you feel like an outsider, by all means agree to it (again) and let's see how well *you* do at following the same rules as the rest of us who have agreed -- or if you can't, stop bitching at those of us who are at least still trying.
Nonsense, the only rule being practiced is utter hypocrisy. The agreement was to treat everybody with respect and stop the insults. Instead it is being used to treat nobody with respect and insult whoever they please under the guise of civility!
