I find the best argument for getting same sex marriage in the comments added to the linked-article saying that there are "pictures' of two maile saints getting married (in St. Catherine's Monastery, wherever it is).
A man says he told his son he didn't need to get a marriage license to live with the girl, it didn't prove love, etc (I had just seen a terrible film, Jude The Obscure, which said the same thing after an eternity of talk and tragedy.) The wise son said yes, BUT if I get the license, I get cheaper car and other insurance rates, etc.
Either we ALL (who drive safely) get those discounts or they are "special rights." and while it is a compromise, until we get the law changed, we deserve same sex marriage to at least get what heterosexuals get.
And that's another thing, some businesses give discounts to people who prove they went to church. As long as they are private businesses, fine, BUT if they are taking taxpayers money that too is "special rights" and should be against the law.
