Ma'am, I like those rules. I assume the apology mentioned in item 9 would be an ironic one. Irony is better than a full frontal counterattack, but surely people who sincerely want to learn something don't need to apologize for that.

May I add to your list?

Don't assume you've won an argument just because you've outlasted the opposition. Maybe your obnoxiousness has driven them away rather than the clarity of your logic. Most people don't see the benefit of beating a dead horse.

Good discussions don't have winners and losers anyway. In a good discussion, everybody wins because everybody learns something. Gracious people show gratitude for what they learn.

People rarely learn anything against their will. Wisdom coated with sarcasm is a bitter pill that hardly anyone will swallow.

It is said that the wise person learns more from the fool than the fool learns from the wise person. "Them that's got shall get..."

Consider posting only ONE message per discussion/argument, and make it a carefully considered one. Then wait and see what happens. If people want to hear more from you, they can ask. If nobody asks, that alone should tell you something.

Wouldn't it be wonderful to hear someone say, "I wonder what [insert your name here] thinks about this?"
