Religion and Politics coexisting together....?

Religion and Politics are two subjects that can be touchy--and when they are mixed, they can be volatile. I used to post and read a religious message board on a regular basis which had a 'no politics' stance. If a poster brought politics into a discussion the moderators would close the thread and bark in red ink and caps 'NO POLITICS'. As is usual among boards, exceptions were made if the person was one of the favored posters; a scholar or long time member--but for the average participant, this was strictly verbotin. They felt, as many others do that we were incapable of discussing religion and politics together without the conversation descending into name calling and vitriol. My hope is that in my posts here, I can do better.
