I prefer to think of this situation as exposing the ridiculous state of current humankind.

There is nothing "normal" about marriage. It is a way of organizing groups of people into taxable pairings, and creating children that will be socialized correctly into the stare's system. Everyone knows that people will love whom they want to love. Crazy ideas of a peron's time in history dictate how the groups are arranged. (Old Testament, anyone???)
It's also been firmly established that the idea of a binary gender is also in the service of oppression. People have always and always will express their personality in the way that is true and real for them --UNLESS that expression is interrupted by systems of control that enforce the rules of their community (in the case of trans people, by killing them). (Multilating intersex babies, included).

So if two people want to live/love- I say GO FOR IT. Want to get married? Sit in a sweat lodge? Have a tea ceremony? That's not my business.
Marriage is a cultural/religious event - like first communion. It's just that the State awards goodies to people who do it- it has nothing to do with anything natural or biological.

The State also awards goodies who play nice with their fantasy that there being only 2 ways of expressing our bodies's truth.
Transsexual and transgender people have always and will always exist. Trans people are natural. The culture we live in now - like most before now - make laws and medical standards that want to hurt trans people- THAT is UNNATURAL.
I prefer to fight the systems that have the power to dimish trans people's life chances. I won't try to squeeze into to somebody else's rituals, nor will I support preposterous ideas of only "coupled relationships" being valid , nor will I promote any gender rigidity, even within one person's life.
