the irrationality of humankind...

Humans have always been strange creatures. We are capable of provoking a silly thing. Imagine a world without racism and religion. We can still find fault with one another for a silly reason. Question is why are we like that? Is there a world where such things will never happen? Are we capable of living in harmony? I guess not. Though this post might be short, but the question still remains. Will we really be able to achieve world peace?
