Sigh. It all really depends on what "flavor" or sect of Hinduism you're following. There are groups that are very "Anti-Other" whether it's prejudice against lower castes, or other religions/cultures.

There are parts of Hindu Scripture that say things like there is not difference between groups, there is only life, and all life has equal opportunity to realize God. But people who wanna be bigots will cherry pick other parts of holy texts, to justify their bigotry.
