Domestic violence has got nothing to do with feminism, as it is usually something that arises from traditional culture or using someone's vulnerability to the abuser's advantage, regardless of sex. It is however widely accepted that the majority of the cases are men attacking women. I do find it insulting that people like you take incidences like this and suggest that feminism is necessary. Im all for feminism but only where it is necessary, such as in the Middle East where women's rights are a joke. If you're a real feminist, fight for the women who are genuinely oppressed.
