Hinduism is the most racist religion on earth.
All because of the holy caste system, which is actually illegal.
But religion is above the law they say..
main castes
1.brahmin (priest class pure blooded and should keep religion alive)
2.kshatriya (Warrior class born as military men)
3.vaishya (business class money makers and who fund the warriors empire and should Donate to the brahmins on auspicious occasions)
4 shudra lower caste( it does all the basic jobs and most people are dark skinned and bigger in population)
5... untouchable (lowliest form of life born (because karma) to clean toilets and do all the dirty stuff, lives out side villages and does labour work (most of the population in this caste has African blood hence impure to touch ))
Untouchables and shudras are denied basic human rights and education.

slavery is bad but castes are horrible

There is white supremacy church...can't remember the name of it.

Mormonism used to have official racist policies; they've since changed them.

Religions are sometimes used to justify racism (like the "curse of Canaan" story), but I don't know of any that actually teach racism as part of their belief system.

I've heard Black Hebrew Israelites were inherently racists towards whites.

Mormonism. God is said to assign skin color according to whom he will come to like or hate. If you're white you're in. If you're black your chances are slim.

Any fundamentalist religion

Mormons are, to some extent. They had a “revelation” sometime in the 70s where they started allowing black men in priesthood, but they still think the reason that we have dark skin is because we’re cursed. 🙄
