That's one of my own personal issues with Anita and her style of criticism. I think there is always room for debate (on some things, especially if we talking about media interpretation). Not even feminists always agree on the things they think are misogynistic. If your approach is that THIS IS 100% misogynistic, and if you disagree you are wrong (and in some areas, you are then accused of being misogynistic for not agreeing)...that to me is the wrong way to approach this.
I say this as someone that considers myself a feminist. And even if you 100% believe something you are saying is right, your end goal should be to educate people to convince them to come to your side, not beat them over the head with it. That's the only issue I take with her series (it not being open to counter-discussions). THAT SAID...with all the whacky crazy people out there, I have no idea if apart of her approach is to avoid these kind of people who don't want to discuss, but burn the whole place down.
