I just want to say thank you to every one of you amazing contributors to this thread. There's so much substance here to take in, process, respond to.
I, too, have felt that there was a femme hierarchy and that "high femmes" (I really don't like that expression. I have heard the "low femme" term, applied by others and as self-labeling, but never in a flattering way.) were on top and I was somewhere much closer to the bottom. My reinforcement for that idea has mostly been from butches, but I've moved on. I decided part of the point (for me) of having the "queer" be part of my identity was what it implied to me about getting to make my own rules. I may or may not be anyone else's idea of what femme ought to be, but I am damn good at being me.
For me, femme is my gender identity, although that is big enough to encompass "woman" and "girl" and "female" as well. You can't take my femme away from me, regardless of what I wear or what I'm doing at any given time. I've been known to wear skirts, dresses, heels, but it's a form of drag for me. I mostly live in jeans or other casual pants (not athletic gear outside unless I am engaging in athletic activity or my house is burning down) and low-heeled boots, mules, sandals. I find that I get more external reinforcement for wearing the feminine drag, from strangers as well as friends and lovers. I've witnessed straight women being rewarded or punished socially for the way they choose to perform femininity as well. I've never considered only dressing up to go to a bar if I was partnered, though, nor do I know that anyone has considered me competition since tenth grade or so.
It saddens me that so many of us have been the victims of vicious femme sisters insecure in themselves and needing to cut us down to make themselves feel superior. I only know of three times in my life that I've been specifically targeted for ugly gossip, once by my (family of origin) sister and twice by masculine queers, and those were rough enough and femmes did participate in the feeding frenzy. If anyone still believes that I hoard man-jocks or am a coke fiend, well, I don't know what to tell you. PM me the juicy bits.

Seriously, though, I avoid those I find to be gossips (in offline life), because I don't like to be around that energy. I find it ugly and draining.
