I am not religious, but I respect other people's beliefs. Many atheists look down on religious people, belittle them, insult their intelligence and make fun of them. I find some "religious humour" to be very disrespectfull; Lars Vilks' stuff for instance, like Christ shown as a paedophile, Muhammad as a dog and so on.
I really do not like that kind of nastiness. Why not treat people with respect and not try to tear them down? I have a Muslim friend and religion is very important to him, one of the last things I would do is try to tear him down.
It's good that people have something that keeps them positive and gives them hope.
Peace and love,
