I am someone who is strongly (fervently) in favor of gay marriage. Single sex adoption has been around for a long time and I had thought that the successful challenge for gay marriage would come when someone argued that the adoptive children of gay parents had a right to have their parents be able to marry.
The Goodridge Case was to me, a fair and necessary decision AND the only court decision I ever read that made me teary-eyed. As a practitioner, I have been dealing with the unequal results of the interface between the Federal and State law ever since. It is clearly a major issue in other states too.
The Commonwealth also has a challenge to DOMA winding its way through the Federal Court system.
I am keeping my fingers crossed!
