The tinydancers of 2065 will be explaining that many Christians were actually in favor of equal marriage. Christianity is going to distance itself from this sort of message as fervently as it now distances itself from slavery.
Perhaps IF the FAGS keep it in their pants, and stop pulling it out to SHOW OFF every time something THEY don't like happens, it might....But until the FAGS discover that sucking each others dick, or licking each others Vagina, is a PRIVATE MATTER, that MOST PEOPLE of any religion, or NON-RELIGION don't want to see, or have their children exposed to, it will be looked on with scorn. You want to be married, fine, go to the local gov't and have a ceremony, have the same entitlements as a NORMAL couple, but don't ask people of religion to condone something that they have not condoned for centuries. Sorry, back to the OP topic!
