It is their responsibility to protect the 'children'. It's funny though, because there is nothing harmful in a Playboy. I know because I've been buying them since I was sixteen. Nothing more than beautiful women naked. And somehow this demeans women.
People say it is obscene.
Its obscene because nudity is linked to sex, and sex is dirty. Especially to strongly religious Christians. I'm pretty sure that's not the way God intended it. He, whoever He is has more pride, and intelligence to do that to them. And you should have the respect to admire his creations, especially one you need as much as the human body.
