Let me get this straight.
You are in a Conservative forum arguing that the State is acting in the best interest of our children, and that's why homosexuals who are unable to bear children are not allowed to marry?
Would you be making reference to the same State that legalizes killing a million fetuses a year?
The traditional institution of marriage is one man and one woman. The states' current definition of marriage is one man and one woman. The states support traditional marriage to protect the many children that result from sexual coupling. Why should that change?
