I'll agree with MZ that you guys should chill out. You are verging on hostility.
In order to perhaps drive the focus elsewhere, I mentioned in my post that I disagreed with your notion (the world would be better off without religion) while still being an atheist myself.
The thing is, you assume that logical thinking concludes definitively that things such as god, heaven and souls are impossible, which makes it false to proclaim that they are real. If god doesn't exist, teaching little kids that he does is misinformation and even propaganda.
But the entire problem is that you can't definitively prove that god, heaven and souls are unreal. You can
believe they are not, through the lack of proof to their existence, but there is no proof to the contrary either. Have you died, and found that there was not a heaven? Do you know every intimate detail of the human brain's working so much that you can rule out a soul? Do you know all facts concerning the creation of the universe, so that you can definitely prove that there was no god involved?
The answers to all of these are no. I am myself an atheist, and I cannot answer yes to any of those questions. The thing is though, I find it more likely that god, souls and heaven do not exist, since I can much easier rationalize those as out-dated human-made constructs, attempting to explain a world we don't undestand, rather than as definitive proof. But still then, I can only believe them to be the case, it is only probability not certainty.
In the end, this means that, to me, religion is subjective and not objective. In the same way you cannot say "Rock music is bad, techno is good!" or the opposite, you can't say "Atheism is right, christianity is wrong!". Your religion matters as much as your favourite colour, in my book.
I will make this clear though, I do not believe that religion and science should overlap. I do not believe that christians should ever look to the bible to answer questions such as "Why does the sun rise in the morning?". We know for a fact that the sun rises due to the earth's rotation around the sun, and whatever the heck the bible might say otherwise is an outdated theory. But pose yourself the question: If the bible consisted of nothing more than the ten commandments and various moral stories (assuming these moral stories contain modern and not outdated "how to treat your slaves" stories), would that hinder science in any way? Would it make for a bad society?
In the end, if I find a person that does good and is happy, purely because of the morals of christianity, what right do I have to tell them that I think they are wrong. They're happy. They're doing good. I should not force my view of the world onto them to change them, since I could only do so for the worse.
And that's why I don't believe that religion has to go. If it makes people happy, and if it makes them do good, there's nothing you can replace it with that will be better. You'll be changing the world for the worse. Does religion need to change its role in the world? In some cases yes. Does it have to go completely in order to make the world a better place? No, I do not think removing religion would make the world better, and for a time it might even make the world worse.
EDIT: Holy 9 posts while I was typing batman. And now people aren't even angry anymore?
