According to you 1/2 Billion Indian non-muslims live in your perceived heaven in Arabic Countries. Does that include Morocco and Ethiopia as well? May they did not teach you that Morocco & ethiopia are Arabic Countries.
Or you mean the GCC? Any way that leaves remaining 1/2 billion Indians in India. Take out 12 percent Muslims out of 1 Full Billion, balance is 380 Million Indian Non Muslims.
So you say that population living in India is 380 Million?
So, go & take lessons in Arithmetics. Even in a Madrassa they might teach you that.
