I don't believe in post-racial or post-gay or post-anything, but I do think within a certain group of friends, what matters less is the specificities of race and sexuality, and what matters more is the shared experience, shared language and shared cultural touch points.
I have never wanted a family. I don't believe in marriage, though I obviously believe it should be legal for everyone who wants to do it. But it is not something I believe in, nor do the characters in my book, nor do any of my friends.
