In regard to discussions of Islam, or any other NC religion, I will quote CAF forum rules for NCRs since some seem to be unable to read it for themselves:
Guidelines for posting on religious discussions
Members are not allowed to be disrespectful of anyone's faith or religion, whether it is Catholicism or not
. If a member is disrespectful, he will generally be counseled first and suspended if he persists in disrespectful postings.
If the nature of an initial posting is blatantly disrespectful to any religion (e.g., "the pope is the anti-Christ" or "Rome is the Whore of Babylon" or "Muslims are terrorists"), suspension may be immediate and without prior counseling.
Members are free to discuss, dialogue, question, disagree with, and debate the doctrines and dogmas of both Catholicism and non-Catholic religions. However, all discourse must be civil and charitable.
For both Catholic and non-Catholic posters:
It is acceptable to question the doctrine or dogma of another's faith
It is never acceptable to question the sincerity of an individual's beliefs
Bringing up historical controversies peculiar to a particular religion should be done cautiously*
It is acceptable to discuss the effect the incident had on current policy or practice.
It is acceptable to seek the truth vs. commonly-held beliefs or conventional wisdom about actual events.
It is fallacious reasoning to use embarrassing incidents to claim that they "prove" a particular religion is false.
Expecting members of any Church to defend or answer for the excesses or extremism of bodies that have broken with it is a technique that has no merit and can't be defended.
*It is our observation that discussion of such past events rarely serves a useful purpose and inevitably opens a thread to posts that violate forum rules and/or the bounds of civil discourse. So, while such threads may be useful, they raise a red flag for the Moderation staff.
