Religion is unusual among divisible labels in being spectacularly unnecessary. If religious beliefs had any evidence going for them, we might had to respect them in spite of their concomitant unpleasantness. But there is no such evidence. To label people as death-deserving enemies because of disagreements about real world politics is bad enough. To do the same for disagreements about a delusional world inhabited by archangels, demons and imaginary friends is ludicrously tragic.
