If a thread or posting on the list makes you angry or sad, consider not responding at all, or doing so in private e-mail. If you do decide to respond to something that has pressed your emotional buttons, do not press Send right after writing your response. Let it sit in your Out box for 24 hours. Then look at it again, and consider whether this response is the one that best enhances your own honor and advances the knowledge of fellow list members. Remember that there are people on this list who are under 18.
Profanity is generally unnecessary.
Sexual references should be PG-rated at worst. Name-calling is inappropriate. Expressions of disagreement should be confined to criticizing the words or ideas of another, rather than the person. You do not know all the people on here, and while it would be pleasant to believe we are all good-hearted and sane, you cannot trust in that. Bashing of any religion.
