The main guideline is simply this:
Accusing another Freeper of being a bigot is also mind reading and therefore "making it personal."
And changing the subject of thread over such things makes the thread "about" you and/or other individual Freepers. That also is a form of "making it personal."
This thread is an example why ad hominems are not tolerable in religious debate.
All of you: Discuss the message - not the messenger.
I will be more than happy to steer clear of the Religion Forum forever.
