I thought Memphis was kidding. If people on this site don't even use the existing Politics group, no one is going to pay good money to be in an empty or near-empty group. And the people on the site with points to spend are generally focused on writing, otherwise they wouldn't have points to spare. There are plenty of places on the internet for people who want to discuss politics. Let's keep this focused on writing.
And there is the Religion & Spiritually group (formerly the Brave - Community of Christian Writers), whose purpose is to give religious/spiritual members a place to collaborate on writing in that genre. By definition, they will discuss religion, although I've stated in the revised group description that debate over which religion is best/real will not be allowed. Of course, if the group doesn't revive, we can just delete it.
And there is John Hamler's small Ballyhoo group for debates, assuming it doesn't peter out. It might catch on if it had a more interesting/obvious name, but it's John's to decide.
