I couldn´t care less one way or the other.
To me it´s a religious matter not a gay issue.
I don´t see the point in marriage anyway, it´s like some people need a confirmation that they belong together, pathetic.
Although in some cases I can understand as many take it as a tradition also.
But as you said aswell, If you and your partner no matter who it is knows you belong together than why bother with any pther crap anyway
