Annie, yes, I think the point I was trying to get at was perhaps similar to Cogito's. There are two elements to bullying. The first is that it is situated within a particular social context of the treatment of minority groups - women and conformity to gender roles, ethnic minorities, homosexuality and so on. Those things need addressing within those particular contexts. But there is also another issue of simple human cruelty and why we don't address that in general. Obviously the two are related. The existence of seeing women as less than fully human can justify cruelty, but the existence of cruelty can justify seeing women as less than fully human.
On an entirely separate note, I don't think it is as much about seeing Jodie Marsh as being the product of the patriarchy or the enemy. I think it is about seeing that Jodie Marsh is no different from any of the rest of us. She may be written a little larger than the rest of us, and is certainly a lot more famous, but she is not from some other category.
I think that is at the heart of a lot of the sexism on MN. A lot of women think that worrying about the impact sexism has on young women is not worth worrying about, because they don't think it will happen to their daughters. Rape, domestic violence, harassment, bullying, sexualisation doesn't happen to women like them or girls like their daughters. It happens to some other kind of girl - a girl like Jodie Marsh. But that is a fantasy; she is all of us and it takes some kind of massive cognitive dissonance to believe that we aren't all just like Jodie Marsh in many ways. And the more people feel able to distance themselves from women like her the safer they feel and the more able they are to maintain that cognitive dissonance. I don't think radical feminists are responsible for that at all.
Sorry if this is a bit incoherent.
