Courtesy and respect is necessary in public discourse, particularly about religion, and being a jerk is a non-denominational affliction.
I don't believe I've seen anyone who was making a real effort at basic respect and courtesy be asked to stop talking to someone. Some people enjoy a flame war, but some don't and some are more sensitive than others. I think you have to respect their requests.
And sometimes stopping the conversation is best for the posters and the forum as well.
You have publicly asked me not to post to you, so I can presume you are including me among those who do not post with "respect and courtesy."
Please provide any post of mine to you wherein I spoke to you on a disrespectful and discourteous personal level.
If you can't provide one, please retract your personally offensive statement.
As the Religion Moderator has repeatedly instructed, we may criticize the belief but not the believer.
