Say "I'm right and you're wrong," with reason and evidence.

Religion shouldn't be held accountable for man's desire to say "I'm right and you're wrong".

OK, but I will hold it accountable when it's holy book tells believers to "strike off their heads and strike off every fingertip of them (referring to unbelievers)." and then the followers do so because their "god's word" told them to. Its one thing to be in the wrong, its an entirely different thing to advocate intolerance and violence.

And what's so wrong with people saying "I'm right and you're wrong," that is, as long as they provide sufficient reason and evidence to show that the they are correct and the other person is wrong. The problem with religion is that the latter is not included in the discussion, it literally falls flat on its face in trying to support itself with reason. Religion should be held accountable when its adherents hold to a dogmatic view and cause harm by it.

And I don't fully share your sentiment that man has a desire to say "I'm right and you're wrong." I don't mind if someone tells me that I'm wrong, as long as they also give sufficient evidence and reason for their claim. That way, instead of being wrong this one time, I can be right in the future, and it also increases my knowledge, which makes my decisions based on more accurate information. This is another fault of religion, it claims "I'm right and I can never be wrong;" with such resistance to change, it is unlikely for its adherents to be swayed by physical evidence and reasoned logic.
