The whole point of the slutwalks is for these women to draw attention to themselves in a sexual way. Why else dress immodestly?! By dressing immodestly.....they get attention. Mission accomplished.
Such is the reigning, secular mindset, which cannot fathom the virtue of Christian chastity at all. Do they think that vulgarity, lewdness and immodesty contribute nothing to the breakdown of public morals? They imitate the styles and manners of the bordello, and they think that they are encouraging virtue and respect for women?
Truly, their thinking, as well as their behavior, is "slatternly" in the extreme.
