“Evil” is first and foremost a religious notion. It means whatever a religion dislikes. - A. C. Grayling

None of the major faiths is bloodless; history reeks with the gore of their wars and persecutions, all the more disgusting a spectacle for being, in essence, as simple as this: A kills B because B does not agree with A that there are fairies at the bottom of the garden.
People should be left to believe what they like, so long as they harm no one else. Apart from normal expectations of politeness, it is not however clear why people should require their personal beliefs to be treated with special sensitivity by others, to the point that if others fail to tip-toe respectfully around them they will start throwing bombs. From a secular point of view, religious beliefs are at best absurd and at worse dangerous, and the amount of free play they are given in the public domain is a menace. Believed-in fairies should be kept at home as an entirely private matter, and their votaries encouraged to cease taking themselves so seriously that, when irritated by those who differ, they resort to Kalashnikovs. Apart from anything else, such reactions speak little confidence in their own violently-held certainties.

The nonsense people talk about cloning stems from the prison-cell of religious belief. Pious exclamations about the sanctity of life, and about not interfering with God’s purposes, conceal a farrago of confusion. Life’s sanctity resides in its quality, not its mere quantity, for there is nothing sacred in suffering. And if we were to “avoid interfering with God’s purposes” we would not use penicillin, nor raise money for the Third World’s starving, nor build a roof over our children’s heads (which, as it happens, Jesus instructed us not to—“consider the lilies of the field”—but not even Christians are foolish enough to obey).

Thus justice is not equality but equity; as Aristotle says, “Injustice arises when equals are treated unequally, and unequals are treated equally.”
