No, this is about women being biologically different. Women don't complain about the gender separtion in physical sports, or that of mind sports. That isn't called sexist. There is no proof that men are inherently smarter, or better thinkers, than women. The closest we have to that is that men tend to be, in general, a tiny margin more analytical thinkers than women. And that is very vague, at best.

For example, woman play seperate from men in the logic-based game of chess. Women are not as good (in general) at tactical/logical pursuits in the context of a game. Maybe it is women that are smarter, as they do not spend their whole life studying a 'game'. A president has to make the right decisions too, not just always the popular decisions. An example of how those aren't the same thing: old situations of civil disobedience being done, such as Claudette Colvin's case of racial segregation, can be easy to see as righ, but would have been unpopular at that time. Women leaders, I feel, are more likely to act in the interests of what she thinks her people thinks she should do (independency versus codependency behavior).
