"gay is the new black" is not a good analogy.

The types of oppression that both groups have suffered are quite different, from a historical point of view. The very valid arguments for gay marriage do not need to rest on this comparison, other than the basic recognition that separate is not equal, a lesson well learned from 100 years of Jim Crow separation of blacks and whites. There is no way that separate can be equal, and we now have the history to prove it.

I think this argument needs to be presented over and over again, that separate is not equal, in the reasoning for rejecting civil unions in favor of full marriage rights, before the entire American public. This argument has traction.

"Gay is the new black" suggests that the black struggle for equality and equity is over, and I don't think that most black people would agree with that, despite Obama's victory. The use of this as a slogan will have the net effect of alienating potential black supporters, I think, as if the unique history of their struggle has become co-opted. The gay struggle for rights is also unique and compelling, but it is a different story and needs to rest within it's own uniqueness, and not rest on other struggles that have great dissimilarities.
