I agree wholeheartedly that every person who is disrespectful should be asked to be respectful, whether they are the first poster, the second poster, the third poster, and more. Usually that is done in private, which I believe is proper.
I believe fully that the above behavior is what we have been asking for. Every person should be responsible for what they post, and every person should post respectfully. I agree completely on this issue.
That should be the purpose of the rules, and that should be the spirit of the rules as well. Every member is deserving of respectful conversation, and every member is held to the same standards of behavior.
