This is an interesting question, and one that is sort of related to something I was thinking about recently--it seems (to me) that many of the alien cultures that are encountered in TNG have a definite "masculine" or "feminine" feel to them. However, it seems that the major cultures in TNG are more on the "masculine" side, like the Klingons and the Romulans. When I say that, I mean they exhibit more traditionally masculine features and cultural concepts--not that women don't appear in both of these cultures. However, that being said, I wonder why the major power players in the TNG universe are more "masculine" in this fashion?
