This is an excellent overview. It's rare to see this combination of concise, readable, and thorough on any topic, let alone on something as complicated as gender. Thank you.
(ps. the links in the "Straight For Equality" paragraph seem to be slightly borked.)
Thank you very much! I try to make things easier to understand while maintaining all the important facts in :)
And thanks for mentioning the problem with the links. All fixed now!
