When I was young it was a different story. Most of popular culture was still Christian and pro-family.
Today popular culture is anti-family and even worse anti-father.
The last thing a father needs to bring in to his home is this toxic popular culture. His children will get enough of that outside the home.
Look at the statements from the father; aside from his remarks about his own bad living, he can barely speak the language of his country! If you have no words, the only thing to do to make yourself heard is to pick up a hammer, a knife or a gun. He passed that on to his kids.
