I've stated this in discussions with members of the board who favor same-sex marriage. My view is that we should grant equal or almost-equal legal rights to such couples. We might even consider civil unions. However, marriage is an institution that is traditionally faith-based, and one which also represents society's best standard of family. In mostly secular communities, then, perhaps gay marriage makes sense. However, in the U.S., which is 85% Christians, and in which over 90% say they believe in God, I just don't see granting marriage as a solemn human right. It's called "holy matrimony." Most Americans see gay unions as less than holy--even if we sympathize those with such attractions.
