But on the other hand to avoid ever hearing such a thing you would have to join a monastry. That is no way to reach the world. Myself, I wouldn't think watching sexually explicit movies is right. But you can't cut yourself off from a person who swears, for example. I believe you can be friends with such a person without condoning what they do.
Music is like the swearing friend.
You can't condone it, but to cut yourself off from youth culture is just being self-righteous. God has put us in the world to be a witness to it, and that means living in the filth without condoning it.
