It is an utter insult towards the fascinating neurons of your cerebral cortex, to believe anybody’s words blindly, even if that person is a Scientist or a Philosopher. So, I urge to you, that you must exercise your own reasoning and judgment (that’s what your cerebral cortex is for; to be specific the frontal lobes) at all times.
Due to the monstrous activity of a handful of extremists, the majority of the human society has been conditioned to believe that the term 'musalman' is somehow synonymous with terrorism. But the reality is, the term 'musalman' refers to someone with 'musallam iman,' that means, a pure conscience. Thus any individual whose conscience is pure and clear, is a musalman or muslim, regardless of socio-religious background. Likewise, any human being who loves his or her neighbor is a Christian. Hence, scriptures can't define your religion, only your actions with other people do.
How conscience tells us that we ought to be fair, nobody knows. This we can say: we don't know it just from being told, we don't know it from the five senses, and we don't know it by inference from prior knowledge. We just know it. The knowledge is "underived.
