I just wish the gay community would be willing to call their unions something other than marriage. I don't care if they want to promise to be together "till death does them part" and get it on the tax benefits, but the term marriage is something that originated in the Bible and is understood to be between a man and a woman. I'm not sure there would be nearly the fuss if they called it a Civil Union and were givenall the same legal rights as people that are married.
There something about marriage that implies being fruitful and multiplying. I guess one could form some type of argument regarding fruit and being able to do math, but then they would need at least a math minor to get married.
