Tom Wolfe: "There was a time when the worst ... slut ... for want of a better term ... maintained a virginal and chaste facade. Today, the most virginal and chaste undergraduate wants to create a facade of sexual experience."
That has been true for a long time. I remember my sister and friends making fun of virgins when, truth be told, several of them were still virgins. It's sad. Shame, stigma, taboo, peer pressure, etc...are part of how a group functions. So liberals who say we should "remove the stigma" are not removing a stigma, just moving it. The stigma is now on chastity, at least to a large degree in the younger set. Same principle applies to all the other areas liberals have "removed" stigmas. You cannot remove them. You only move them.
