If it has nothing to do with the church, why do they demand it be called "gay marriage?" Why not a "Partnership" or a "civil alliance" or any number of other terms? Why not, as you say, make it strictly a STATE issue? As I said in my earlier post, I believe gay couples should have all the rights of a married couple... I just don't think it should be called a marriage and no church should be forced to recognize or accommodate it.
The big problem, of course, is that once a civil ceremony takes place, once it becomes accepted, there will be lawsuits filed against churches claiming bigotry or bias and try to force churches to recognize, accommodate or even participate in a gay "marriage"
