The Times, They are a'changing

Yesterday, while registering for a website, I was asked to provide some basic demographic info. I was given three choices for sex:  Male, Female, and Transgendered.I'd never seen that option before and my first thought was actually--Seriously? The option just seemed so earnestly PC, almost as if the website was trying too hard.
It And then I thought of Bob Dylan's song, "Don't criticize what you don't understand."
We live in a world that can no longer be defined by either/or. First there was LGBT and now there is QUILTBAG, and maybe soon, labels like these will be totally irrelevant.  It's time, in the words of the classic Apple Computer slogan, to "think different." And maybe that paradigm shift begins with a third choice on a website registry.
