It has nothing to do with Biblical scripture, unless you assume that gay "marriage" is the norm in Buddhist, Hindu, Shintoist, and Islamic societies.
The fact that homosexuality is unnatural is enough reason to not sanction homosexual "marriage" (and I put marriage in quotes because two people of the same sex can't marry).
Homosexual "marriage" does indeed lead to a loss of liberty for the majority population. It will lead to additional federal and judicial control of education. It will lead to loss of tax exempt status for churches which don't obey government dictates on this issue. It will lead to more laws telling people who they can hire and who they can sell or rent their own property to. It will lead to more government control of private organizations. It will lead to more regulation of speech. It will outright override religious liberty for many business owners. And so forth.
It will also lure more children into the gay subculture as these unnatural pairings are prddled to kids in the public schools.
It's as ludicrous to sanction a "marriage" between two men as it is to sanction a "marriage" between a man and a Toyota, or a man and a water buffalo. Marriage **IS** the bonding of male and female. Gay "marriages" are simply play-acting.
Assuming you're a caucasian male, do you find other men equally as sexually attractive as you find Japanese women? If not, then you should be able to see the difference between same-sex "marriage" and interracial marriage.
TYPO: prddled should be peddled. (I need glasses)!
