Oh wait a minute, they don't do that at all. Silly me.
What they're actually saying can be summed up by, there are good girls and there are sluts. You want to be one of the good girls don't you? So cover up your perky young body so the boys will ogle, harrass and grope and slander "those" kinds of girls but end up marrying you.
And we're not going to question why it is that it's ok for men to go around screwing who they want and treat them like shit afterwards, while it's not ok for us to fuck at all, because it's not out place to. Men have their needs, and their needs must be met.
So we'll wear our "Girls Gone Mild" t-shirts to show how strong and independent we are, while those horrible feminists go around wearing what they like, fucking who they like, and then having the nerve to say they have the right to be treated like decent people, just like the men are!
