Dear whomsoever! let us forget about past but today you just pick up one guy from your people who hates Brahmins and take one brahmin guy. Give one book to each and place them in the same environment to read that book. next day, take a written test of both guys and you know the result. your guy canot not make it without the caste certificate. now tell me how many years you need to compete with brahmins. It is the religious teachings which always keep them up.
