Of course the sexist, demeaning commentary is inexcusable and unjustifiable, but how people are regarded by others has a bit to do with how they present themselves. When people are sexually procative for the sake of attention, what do they expect the nature of it to be?
I would still expect to be treated with respect, like anybody else. That is not too much to ask.
Attention is fine. Disrespectful attention, lechery (as you stated before), and dismissing violence against somebody is not fine. I disagree with the notion that when somebody displays himself or herself as a sexual person, it automatically allows disrespect.
I think the idea of "If you're going to act like a ****, then don't be surprised if you get treated like a ****" is inexcusable. First, it speaks of how people are conditioned to see prostitutes and promiscuous women as "non-people", and assumes that the natural reaction to promiscuous women and prostitutes is one of violence and/or public shame and objectification. Second, the nature of the responses is a manifestation of ****-shaming. The vast vast majority of the responses do not celebrate the women nor do they respect them.
IOW, I disagree with the notion that the women in the pictures brought on the disrespectful comments themselves.
