To be serious, I'm not a fan of marriage of any kind. It is an opportunity to make oaths/ vows that can be broken and cause emotional and social harm over the long term, as participants mature into new understandings of life.
Obviously, I see the need for some people to have the security blanket of marriage. They just have too much religious and cultural baggage to live otherwise. It provides a cover for the state to take control of our sexual and parental lives, as well, under the current state-centric configuration.
Under the Kingdom conception of life, espoused by Jesus Christ and lived out by the Dalai Lama, Mahatma Gandhi, myself and many others, we seek to abolish the state in favor of a libertarian stateless society driven by conscience (The Kingdom). Marital decisions under this Kingdom approach are by conscience and not by state permit. Thus, gay marriage is up to the participants in Jesus Christ's Kingdom conception of life.
"Judge not" -- make no legal determinations of others.
