Homosexual relationships do not produce offspring without heterosexual input. Therefore, assuming monogamous relationships, as the ratio of homosexual to heterosexual relationships within society increases, the ability of the society to grow decreases.
If a society cannot maintain a 1.2% growth rate, they decline and within a few generations suffer from complete societal collapse due to not having a large enough young, productive, youthful population to sustain the old, and continue to the next generation. It's all in the numbers. "Gay Marriage" then becomes damaging to the growth of a society, and therefore is damaging to the future of the society, and reduces the "will to power."[/quote]
Thats a horrible argument...if someone is gay then how exactly do they produce offspring in the first place. They are already gay, nothing is really going to change that fact. Two gay guys living together aren't suddenly going to be able to have kids just because they can't get married.
