Blazing Giants, it does matter. Because if some people have marriage, with all the ceremony and celebration and legal rights, and others have civil unions, with maybe some rights, you don't have equality. I know same sex couples who had registered civil unions/domestic partnerships and it had all the excitement of renewing their driver's license. Just a bureaucratic form. But these same couples broke into tears when they were married.
Many same sex couples have religious, Christian or otherwise, marriage ceremonies. Only someone as ignorant as SlyPokerDog would think you are either gay or Christian but never both.
Marriage is both a legal right and, if desired, a religious rite. The state issues marriage licenses, which entitle the holder to all legal rights and responsibilities. Clergy are empowered to perform the ceremony for those who want a religious blessing; the marriage is legal without it but the couple may not be married in their faith otherwise. No clergy are required to perform any ceremony they don't approve of. No one can force a Catholic priest to marry a divorced person or an Orthodox rabbi to marry a Jew to a gentile. The decisions are about what the state honors, the legal right.
Yep, checks and balances, funny how those who often claim to be Constitution lovers are unaware of the third branch of government. Just like those who claim Christianity are so often unaware of things like loving thy neighbor and those without sin casting the first stone.
What a miserable life SlyPokerDog must have with such a mean, petty little soul. To be outraged at others' joyful celebrations. Humans are social animals. We evolved as group living primates; as such, empathy is an adaptive value. It may sound hokey to say "smile and the world smiles with you" but in fact that is true; we are biologically adapted to respond in kind to others' joy and sorrow. Sadly, social prejudice can overcome this adaptation, hence you have the supporters of Prop H8 who cheered when anguished couples wept over their canceled weddings and people like MarAzul who grouse when others celebrate. How sad.
