Caution!: Opinionated rant!
I'll step out of line here and say I really don't like these things..
I'd like to be in a female led relationship, but that's what works for me. I expect other couples to pursue what works for them, and it's none of my business what they want to do.
I don't like the idea of societal matriarchy any more than I like the idea of societal patriarchy. This idea that one gender should be in charge is a crap idea (IMO). People should just get along with people (or at least try to) and have fun, regardless of age, race, gender or any other perceived difference.
For me, colonies and organisations of female led couples smacks of bitter feminists who really believe that there is still some glass ceiling stopping women from being equal. I can't see that, at least in the world I live in. Certainly, in many fields women are better off then men. Want to work in hospitality in Australia? You've got stuff all chance if you aren't female. Male nurses are still looked at sideways too.
There are probably plenty more examples, but the idea that a man doesn't have an equal chance of getting a job as bar staff, but a woman does have equal chance of getting a job driving a truck is inequitable.. but yeah, feminists wouldn't hear of it.
While I'm beating up on feminists

I reckon they're responsible for the death of chivalry. If you're truly trying to achieve equality, the idea that men should open car doors, and put coats over puddles for women, will have to go by the wayside. In this sense, feminism has done a disservice to Femdom relationships.
Just some thoughts.. don't anyone take it to heart. Like I said, I'd rather we all just get along and people do who and what they want.
