By the time last Friday came, the same-sex marriage debate was no longer about sex and had very little to do with marriage. Rather it was anchored in a redefinition of human identity itself. In the new world order, it is the individual, not biology or God, who determines identity. We are now “selves” of an increasing number of varieties and we are decreasingly male or female in a biologically meaningful sense. One day soon people will cease to use “same-sex” as adjectives for marriage. Every marriage will be the same: Selves who take vows. Two selves. Perhaps even three selves or more.

Moreover, “selves” won’t be limited to human relationships. Professor Sherry Turkle from MIT has written of the question of marriage to a robot. Marriage with animals is tomorrow as well, because it is already today in some places.

.. Again, this is not simply about who gets to use which bathroom. This is about something as fundamental as human identity. You may choose to ignore or to dismiss this. But it’s not going to ignore or dismiss you. As Kuehne put it last year, this is where the debate actually is. It is now down to the fundamentals of human identity.
