I'm not asking you to sugar coat anything. But just saying anything you think isn't remotely productive, it doesn't help with anything. The way I see it, there are three possibilities:
1. You are unable to filter yourself. The lack of a filter is immature.
2. You are able to filter yourself, but choose not to because you think that being right makes it okay. A self-righteous attitude is immature.
3. You think the rules don't apply because someone else broke them first. This is known as the "he started it" way of thinking, common among second graders.
Your attitude does not help anything. We should be striving to maintain a peaceful community, not a hostile one, and you should make an honest attempt at that rather than saying "it's okay because I'm right".
Not to mention, the rules specifically say "Don't Be a D*ck". If you cannot be bothered to follow the rules, be prepared to be dealt with in the same manner as any other rulebreaker. It's nobody's fault but your own if you can't figure out what constitutes appropriate behavior.
