Interesting post, I think gender is a super interesting topic right now. I just wanted to mention one thing regarding your post, where you mentioned how Muslim countries deal with gender. I don't know if you're aware of this but currently in Iran if a homosexual couple wants to date publicly the only way they can do so is by one of them getting a sex change. It is encouraged and funded by the government because they have such an intolerance for gay people. Some people have said they are being very progressive by doing this but it's sad. If someone wanted to change genders it would be great but it's essentially forcing it by giving people a way to be with the ones they love. Theres a good documentary about it here:

Also regarding the vapogender stuff.... I think some people are confusing personality/moods and gender.
