Have no fear, the Good News Club is in no way attempting to create a national religion. It is simply a voluntary gathering for children trying to use a facility that their parents' tax dollars helped pay for. Reading this paper, I was left with the impression that Pastor Fournier was going to be lurking in the hallways waiting to drag unsuspecting children into the cafeteria for a quick session with the thumb screws. Religion is already in the schools. Any kind of world view can constitute a religion.
Schools provide their students with some kind of world view.
You just need to recognize it's already there and deal with it. A karate club or a yoga class will teach a world view. The problem here is that the Good News Club is a Christian organization, and that's what some find objectionable. You have the right to disagree with Pastor Fournier, but make a reasonable, substantive argument. Remember, the Supreme Court agrees that Pastor Fournier has raised a valid point, so if you want to discuss this case, at least try and address these issues.
