Well, I have tried to stay away from this discussion so far but after reading your post, I thought I should share my bit...
My kid who goes to Kindergarten is 4 years old, i drop him every day and notice there are African, Asian, Norwegian and South American kids and my son has a very strong bond with all of them. Watching their chemistry and friendship makes me realize how come we learn to hate each other because no child ever gets it from his/her mother's womb. And then when I see the blood shed all over the world, genocides going on in certain regions, wars, military mights bombing the sh!t out of other countries for one reason or another and one particular trying to bully all the rest of the world, I ask myself and everyone here is it religion or atheism who is to blame for that ?
There is a Kindergarten in a Norwegian City where a kid comes back home and her mother notices one day that his sons ass hole is unnaturally wide. After she filed a complained and Police did inquiry, it was revealed that a certain male norwegian teacher in Kindergarten was fulfilling his sexual desires with 3-4 years old kids. I will punch the face of a person who will relate this to religion or atheism.
I can't recall one example where a religion or non-religion system has sustained for a longer duration of time while being beneficial to the humanity, maybe wee need to take a look at ourselves. There are always elements who take control of the system, manipulate it for their own interests. I can understand people being annoyed or put off by the idea of Supreme Being for not interacting or interfering over all the evil and bloodshed going on in the world. Maybe instead of blaming we should take some of the responsibility for all that is going on. Blaming religion or atheism for all the evil, hate and bloodshed in the world because we are so devoted to our own opinions and beliefs is just ridiculous.
