Feminism =/= liking every female character
I define feminism as the idea that women should be treated as full and equal human beings. This in an idea I happen to support. In addition to this basic idea, I support a number of related ones, such as a woman's right to make her own choices in matters such as lifestyle, education, sex and reproduction.
I do not define feminism as holding a particular opinion on Ginny Weasley. I find her boring, annoying, a bit rude, and occasionally mean and aggressive. She has some redeeming qualities, especially when she's not proving how Ideal she is, but I don't like her much, and I strongly *disliked* H/G in HBP. I didn't see any conflict between my beliefs about women and my opinions on Ginny and H/G.
I am beginning to sound like a broken record, but real feminism doesn't mean never criticizing women. Even 'strong, independent' women who strongly and independently worship the hero for being the Boy Who Lived. I'm not going to be a good little feminist and pretend I like someone because she's female.
The brand of 'feminism' that requires me to like Ginny, Movie!Hermione, and the Pink Power Ranger is a fake. It simply substitutes a new 'ideal woman' for the old one. I must not speak quietly, I must not be demure and unassertive. I must exercize my sexual rights, not abet the patriarchy by being monogamous. My mother must go to work, even though she can afford not to, because otherwise she is useless (nevermind that she does more good than most paid social workers-- if she doesn't get PAID, it doesn't matter that the kid with the broken arms didn't have to walk home). A woman who embodies this new ideal-- who is smart, tough, powerful, aggressive, sporty, outgoing, and quick to speak her mind-- deserves to be admired and praised. We are even supposed to admire Bellatrix for being a 'strong woman' (okay, she tortures teenagers for fun, but at least she's not a HOUSEWIFE). This isn't feminism. This is valuing a woman's mannerisms and personal preferences over her moral character. I don't care if you agree with me about Ginny (or even Bellatrix) but don't tell me I'm aiding patriarchal oppression by not living up to the latest image of the Ideal Woman.
