Viviane,
You make some valid points. Please remember that I am just relaying what I heard on the radio. It's no big secret, it was Rush Limbaughs show. I heard that a couple of months ago, and as I do not have a photographic memory, I wasn't quoting verbatim. Those may not have been the exact words Limbaugh used but the meaning was the same. I should note that I am NOT a ditto-head, I do not listen to him very often and I do not agree with everything the man says.
Again, I am neutral in this battle, but please let me ask you this, you are right, churches are not (supposedly) a business. So, not being a business, don't they have a right to decide whom they choose to wed? If a couple of Catholics ask a Jehovahs Witness to perform their wedding ceremony in the Kingdom Hall, I'd be willing to bet that the elder would graciously decline (not before offering them some literature and a free Bible Study, of course!)
Is that actually discrimination? Don't most religions cater to those of their own faith? (I know JW's are not really a religion, they are a book publishing business) but c'mon, play along here for the sake of the discusion!
