I often disagree with Jonah Goldberg and the rest of National Review on social/cultural matters but I think he nailed it here:
So, imagine you’re a young Saudi guy logging on to Facebook for the first time. It asks you to state your gender. It then gives you 58 options. You take out your fingers — the simple man’s calculator — and start counting along. Male, female, whatever uncle Ahmed is . . . okay three. I count three.
What are these other 55 things?
You might think: Maybe those burkas don’t just cover women?
Then again, maybe it is better that trans-ethnic, otherkin, furry-bronies publish their headmate's identities on Facebook so the rest of us can be better prepared if we encounter them in what we call real life.
