Unfortunately, the bumper sticker in question encourages such atrocious behavior - without noting that only a minute fraction of such amoral people do in fact make history (and many of those the wrong kind). Ask the car's owner if she wants her daughter to take that advice to heart and become a drug-addled 'ho.
First, I don't think I'll be asking her that question. But it is interesting to note that she now has 3 daughters with the oldest currently a home-schooled four-year-old. I pray for my bother...
