I have one rule: no expressions of anger. Anger is triggery for me, if you know what "triggers" are. I encourage you to disagree politely and express rational arguments. While I agree that anger can be a very useful tool, it is not one that you are permitted to use in my space. Curses and profanities used emotionally are not allowed. Insults at other commenters or people whom I know in real life are not allowed. Violations may result in a mild public rebuke, freezing the thread, unfriending, and/or banning, depending upon the severity of the violation and the level of warnings beforehand.
