As expected, there was a rush of praise from the LGBT community, and condemnation from Fox News and its reactionary brethren. On further analysis, I believe this is significant progress yet not as momentous a change as some imagine.
A few months ago I was filling out an online customer survey. Under "gender," in addition to "male" and "female," there was a third option: "other." I thought that was impressive. Then Facebook came along and added 50. Bravo, Facebook, bravo.
At 17 I have a lot to worry about: graduating from high school, keeping in touch with friends, staying out of trouble, dealing with sexual issues, etc. But who thought I would have pressure from Facebook to decide whether I am male or female.
