What you've said makes no sense at all as up to 85% of Sweden citizens are atheist, along with Japan, England, France, Finland, Czech Republic, Australia, Norway, New Zealand and most of the other developed countries all share a high rate of atheism. As a matter of fact all of the most developed countries in the world have a high level of atheist/agnostics with America being the exception as it is the largest Christian nation of the planet. If people needed a deity to worship in order to have high morals why do these countries all display a sense of harmony and good living standards in comparison the the rest of the world?
Where's the evidence to suggest that atheist/agnostics are less moral than the religious? You won't find any because it doesn't exist.
As for Africa, it is a very religious country and that is contributing to their problem. With the Pope declaring that condoms be forbidden and that jerking off is a sin, is it any wonder that most women are contracting AIDs from being raped. A good percentage of the populalation already have AIDs and while HIV meds are not given to these people the Vatican stands watching this with arms folded, it's pure evil. I don't need to get into the Islamic side of things as we can agree on the level of evil that they're capable of. I just handle my resentment for Islam in a different way than you do.
I don't understand how you can possibly believe what you have just said.
