I didn't read that post as GN saying that a handful of women on the internet will be to blame for it going wrong, but that if you have women who belittle other women being the identified face of feminism its damaging.
The message is pretty simple - women are equal to men and should be treated as such, but somewhere in all of the anger and name calling, that message is being lost and a whole new generation of young women are staying away.
Now my head is stuck on a loop with "whatever happened to the female president -- she's dancing in a video next to 50 cent". Damn you Pink and damn the bottle of white I've drunk this evening.
