I was told the exact opposite of that in my Positive Psych class. I remember multiple sources being cited but the only one I could find in the time I'm willing to devote to this conversation was a 2006 gallop poll thats mentioned in "Happiness" by Diener and Biswas-Diener. Anyways the countries that scored highest on happiness tended to also be high in gender equality.
Do you have any way of finding that poll and linking to it? An actual poll would very much outweigh a half-remembered unverifiable source.
Upon reading Eliezer's possible gender dystopias ([catgirls](http://lesswrong.com/lw/xt/interpersonal_entanglement/), and [verthandi](http://lesswrong.com/lw/xu/failed_utopia_42/) and the other LW comments and posts on the subject of future gender relations, I came to a rather different conclusion than the ones I've seen espoused here. After searching around the internet a bit, I discovered that my ideas tend to fall under the general category of "postgenderism", and I am wondering what my fellow LessWrongians think of it.
This can generally be broken down to the following claims:
EDIT- Due to some really insightful comments;
I replaced men being prone to aggression as a negative, with men being prone to suicide.
I made the verbiage a little more explicit that no one would be *forced* to change, but would seek out the changes that transhumanism would have available.
