Feminisim to me is about equality, choice, and recognition. It would take pages to elaborate further, and I leave that to others.
Submission isn't taken it is given, it is a choice you make, a gift you choose to give. You have as many rights (and in some ways more as you are able to set your own limits) in the relationship as does the dominant partner.
Why do we insist on a label. Men don't say they are masculinists. I personally just like to use the labels to get a rise out of people, push thier buttons, stir the pot so to speak. I was called a Fema-Nazi once (ok more than once...in fact still get called that quite a bit) and rather liked it. There is still much to be done in the name of the "feminist movement" but bringing feminisim into the bedroom, playroom, dungeon or wherever you play is not where it is needed.
