> Can you tell me one other religion which has the concept of caste in religious scriptures?
They may not be having caste-based discrimination but they do have other forms of discrimination. That's why you have terms like heathens, heretics and kafirs.
While I agree that Hindus have more of this caste-based discrimination, a simple search shows that it's not exactly uncommon in other religions in India.
Funny you mention heathens, heretics and kafirs. All of these are people who are non-believers in their corresponding religions. Dalits are actually believers in Hinduism. No other religion in the world discriminates against the very people who chose to adopt it, except Hinduism.
I'll reiterate, it's very rare in other religions and uncommon. Mostly remnants of Hinduism. But ask an average muslim or a christian his caste and he will say that he doesn't have one.
Those terms do mean non-believer but they are also applied to followers with slightly different beliefs. Consider protestants, shias, ahmadiyas etc.

Almost 80% population of India is Hindu. It's obvious that relatively less number of muslims and even less number of christians are gonna talk about caste.
