This Slate article (from the XX Factor section) begins:
Sarah Palin calls herself a “hockey mom” and “as pro-life as any candidate can be” — but not, as far as we know, a feminist. And why would she? Feminist has long been a dirty word for conservatives, and so it’s not their label for her, even though it describes Sarah Palin to a T in so many ways: the working mother/ crusader/ political activist. Margaret Thatcher didn’t use the “f” word either.
I should note that the Anchorage Daily News reported in August 2006, when Palin was running for Governor, that “[Palin] is pro-contraception and said she’s a member of a pro-woman but anti-abortion group called Feminists for Life.” So it seems that she does call herself a feminist (and rightly so, in my view).
