Again (IMO) I think one of the reasons is that India is so diverse. It’s been led by rulers of various religions. I remember hearing (and my told me as well) that India has had Muslim/Sikh presidents. Although…it’s the prime minister that seems to hold more power than the president and I wonder how diverse that has been. At the same time, India is not completely devoid of prejudice…example: the caste system, and skin color bias are issues there as well.
