Quite simply, the Quran teaches supremacy, hate and hostility.Consider the elements that define hate speech:
Drawing a distinction between one’s own identity group and those outside it
Moral comparison based on this distinction
Devaluation or dehumanization of other groups and the personal superiority of one's own
The advocating of different standards of treatment based on identity group membership
A call to violence against members of other groups
Sadly, and despite the best intentions of many decent people who are Muslim, the Quran qualifies as hate speech on each count.
The holiest book of Islam (61% of which is about non-Muslims) draws the sharpest of distinctions between Muslims (the best of people, 3:110) and non-believers (the worst of creatures, 98:6). Praise is lavished on the former while the latter is condemned with scorching generalization. Far from teaching universal love, the Quran incessantly preaches the inferiority of non-Muslims, even comparing them to vile animals
