Why is she assuming a marriage certificate will improve the health of two gay men? It seems to me the problem is that there are no complementary traits like those that exist in a male/female marriage - a reason that proves the natural law theories that have been believed forever.
Two males (especially 2 males - not 2 females) might naturally come to tensions because of a natural characteristic of wanting to be the alpha person in the duo. Heck - that happens in all the animal kingdom too. I guess that explains why in nearly every same-sex relationship, one assumes the male - dominant role and one assumes the female-submissive role. But that is not normal, no matter how it is characterized.
There is simply no logic in same sex pairings. It is not sensible biologically/physically, mentally and or spiritually.
From what I hear the gay men are more likely to have 'open' relationships and the lesbian (not sure what variety) are the ones more likely to beat up or get beaten up by their partner when hit with stress. just what I have heard
