arguing over any religion is madness,because belief is not based on facts, when you apply common sense, every religion fails.
Belief= an acceptance that something exists or is true, especially one without proof.
History is always written by the victors (people in power, in the case of 1971 war ), which most of us recently found not was big lie.
Now imagine that, for all your life you beliefed in something and did few acts (e.g. Kashmir Jihaad or drinking animal urine in the case of Hindus) and just before youy die, you found out that it was all a big lie....
So whatever satisfies your brain and thinking,thats good for you, but taking extreme position is belief is pointless.
