You mean, “Which has no caste system and untouchables or Which has not exterminated the ancient cultures of South America?”
Or do you mean, “Which is the religion whose followers established colleges, universities, and hospitals all over the world, or whose followers taught the world that there is only One God Who is called by different names by sifferent peoples and asked us to respect all religions?”
Never Compare/Contrast Religions for (any) God’s sake!
Every religion has its glorious side as well as its gory side.
Appreciate the first and ignore the second (if you are an outsider).
Embrace the first and to try to correct the second, if you are an insider.
