There are some quite well documented differences in women's personality traits - particularly surrounding sociability, agreeableness and neuroticism. It's not particularly contentious to state that men and women have differing personalities. What may be contentious is the conclusions you derive from that.

Incidentally:

1) An environment filled with intellectual posturing is not "hyper competitive". The fact that you could confuse the two is concerning.

2) My post may have seemed to you to make a set of assumptions about women's abilities but it didn't (just their preferences).
