The point is, being a Christian does not mean hating or belittling the non-Christians. Being a Muslim does not mean hating or belittling the non-Muslims. Being an Atheist does not mean hating or belittling the religious people. In a civilized society, diversity in religious orientation should be the reason for celebration, not the cause for hatred and differentiation.
A religious individual may most gloriously carry out his or her own rituals, as a part of his or her cultural identity, but the moment, that person starts to build a wall of separation between the self and the rest of humanity, coaxed by the textual commands of a scripture, the healthy religiousness turns into dangerous fundamentalism, which is a threat to both the self and the society.
Any individual whose conscience is pure and clear, who can think for himself or herself, is a musalman or muslim, regardless of socio-religious background. Likewise, any human being who loves the neighbor as much as his or her own family is a Christian.
When a person irrationally and quite pathologically sticks to the creeds of his scriptures too much, it can turn even a great human being into the worst version of himself.
To the representatives of theoretical Islam, i.e. Islamic fundamentalists, the Jews, the Christians, the Hindus, the Buddhists and all other humans who are not Muslims, are not just object of extreme detestation, they are, at the worst, lesser humans of false religions. This is not religion my friend. This is primitiveness at its worst.
Scriptures are meant to serve humanity, not humanity to serve scriptures.
