Of the many forums I belong to, there seems to be two schools of thought about handling the ever present, and ever problematic "religion and politics" type issues. Some forums have a Religion and Politics area, enter at your own risk. Others unequivocably ban religious and political discussions, and make no excuses about it.

On a side note, most forums have "on topic" and "off topic" sections. Topics always seem to find their way into the other section.
