Whenever someone says "domestic violence" people always assume that the man is the aggressor, and the woman is the victim.
If Ross Kemp had hit his wife, I doubt anyone would say she deserved it, they'd be baying for his blood.
IMO, these double standards are drilled in to people since they are born. People accept women as the weaker gender, who are so much more delicate than men. If a man hits a woman, there's an uproar, if a woman hits a man, it's shrugged off, because sweet, delicate women NEVER hit a man without due provocation, surely?
