Funny, I live with a college-age daughter who is an outspoken and studious third-wave feminist, and has been politically active since she was ten years old. She doesn't talk about radfem at all, or anything close to the "ultra-feminist" caricature. The third wave feminism I listen to constantly is about correcting the limitations of second wave feminism (Gloria Steinem style) and expanding our awareness and acceptance of more fluid gender roles in today's society. Nothing radical about it.
