What I personally have observed is that there are plenty of men and women who have a need or desire to be dominated. And that a minority of these people can't deal with the idea that it's "just" a sexual fetish or personal quirk, but must convince themselves instead that the entire world would be happier or much better off if only our entire society were male supremacist or female supremacist, accordingly.

I've also observed that there are plenty of people who have a leadership or followership preference in a relationship... but the desire to be the follower is both more widespread and more gender-balanced than the desire to be the leader.

So I guess what I'm saying is, the fact that there's a large unsatisfied market of females wishing to be dominated (sexually or otherwise) should NOT be mistaken for an indicator that this is somehow "the way the world should be".

That market is unsatisfied for the same reason its male counterpart is: there simply aren't enough people of either gender with the inclination, experience, self-awareness, etc. to meet the demand.
