Religion is a set of rules devised to bring order to society. The concepts which science could not explain religion explained it through philosophy and superstition (snake swallowing the moon..etc). Man as we learn we should redefine our views and bring in new set of rules. I am simply not going to follow EVERYTHING some guy defined 2000 years ago.
In the meanwhile, some people claimed and still claim to be closer to GOD than others, devised the caste system and preserved it to their kin’s advantage. This was very easy due to language differences. You are the only one who knows a language, which has no economical value in the society. So no one in the society have any incentive to learn that. You claim it to be the language of the gods. So others who don’t know it become your less equal folks.
GOD created every man and woman as equal. There is no need for any local interfaces. I think India would better off it if people who preach superiority of language, race, language, religion, caste or region to be shipped to the Dashin Gangotri Indian base in Antartica and left to the cold wilderness.
