I identify so much with this. Hypatia and I went to see Julia Serrano at a talk she gave about her book,
Whipping Girl, which addresses this issue. I've always been very feminine, but I've only recently realized I was lesbian, so I haven't really experienced discrimination against femmes in the gay community yet.
I have definitely experienced hostility against my femininity in the straight world though, whether from feminists or not. People take one look at me and assume I'm weak because I look like a stereotypical throwback to pre-feminism days: quiet and gentle, wearing dresses.

I am a feminist. I am strong. I also happen to be girly. So what?
I'm glad other women are starting to speak out about this.
