i haven't followed your posts on gay marriage closely so sorry if you've laid this all out before. But would you support doing away with government-sanctioned marriage altogether? Replace with "civil unions" that are the legal equivalent, except broadened to include every type of human relationship--so if me and my bachelor pad roommates want to enter a civil union and get hospital visitation rights, we can do that. Eliminate tax breaks and only allow one designated person to have access to traditional monetary benefits. If necessary, impose certain costs (i.e. a license fee) on the civil union contract to prevent abuse.

basically the idea is to detach the concept of family from outdated notions of gender and genetics.
