There has been a good deal of discussion, coming both from the left and from the right, about the need to move past what is called Identity Politics, discussion to which I have on occasion contributed on this blog. Here is a heartfelt and well-written discussion of the question in the form of a family history of the author, going back to slavery times. The message of the piece is a simple one: Turning away from Identity Politics is a luxury that White people can afford but that people of color cannot afford. It is a luxury that men can afford but that women cannot afford. It is a luxury that straight people can afford but that LGBT people cannot afford.
It would be worth your time to read it, I believe.
