I guess a lot of Christians need an evil power to keep people in place - though certainly not all. Some go by the love message.
If you mean this guy, he is trying to fight both I think.I find it rather bizarre that they try to fight one superstition with another, rather than using rational thought and evidence. I'm beginning to think that the world is getting nuttier by the day. I dread the thought of fighting the idiocy my grandchildren will have to face as they grow up.
I don't think you need worry about your grandchildren, there are more atheists every day, and by showing the way they could give also religious people freedom to break away from oppression and dogma and to shape their own religion, if they want one. Individual religions are good for some, and no problem for others.
