Here's my take on the whole damned issue.
I don't give a flying **** what you find attractive. You wanna screw dead goats, go right ahead. God told you the deal and if you don't want to listen you can burn in hell for ever, for all I care. Marrage? Last time I checked I had to pay the state for a licence to get married. Give that shit to Ceasar and go all ghey if you want, but where does it say the Church is required to marry you?
If the law of the state says you can marry your pet cat, then so what? Have a great time. I could care less. If the Law, voted on by the people, says Man and Woman only, then shut the **** up and move the **** out. Last I checked your right to happiness says you can persue it- you don't just get it handed to you, you ****ing little whiny sum-bitches.
