Take a lesson from CBS’s Rules of Engagement by Michael Rossellini.
Here’s an excerpt:
“…no libel, slander, no lying, no fabricating, no swearing at all, no words that teenagers use a lot that some people think aren’t swearing but we do, no insulting groups or individuals, no ethnic slurs and/or epithets, no religious bigotry, no threats of any kind, no bathroom humor, no comparing anyone to Hitler, Stalin or Pol Pot. We expect heated, robust debate, but comments should be polite and civil. We consider this to be public space so behave and write accordingly.”
