Yes all the practical things that others have shared here, taxes, care-taking, visits in hospital, survivor benefits, etc are all great gifts to have. These are social and human rights actions not institutions, these are rights of all people. 

All of this struggle to gain marriage rights has taken our attention away from who and what gay people are… I use gay people as all inclusive, maybe I should use queer… anyway. 

Our being gay sets us aside from the rest, our gayness is our gift to the world, our spirit is many gendered, and all gendered… 

We have sold our gayness to corporate America, we have given our Pride events to banks, beer makers, insurance company's. A pride event is suppose to be a March, we are rebelling in a peaceful active way. Being ourselves, creatively, joyously while saying, we are here we are queer and we are not going away, see us, here us… 

Let's march for human rights, equal rights for all humans, not just our right as gays to get married, but to assure everyone has a right to visit their sick Lover, be granted their inheritance of years/time spend together. rights to claim, their partner as their partner…
