Not sure why so many have an obsession with posting a picture of themselves. Seems to be inundated with a lot of exhibitionists. Seems like the days of trying to pass as the opposite sex are gone, and they want the world to know about their "special" identity.
But either way the result goes, it's a stupid Twitter poll, and shows how insular people are that they're battling over something like this. But I suppose when you invest so much in a labels, base an entire identity around a label, you're not focussing on reality.
