All your analysis is completely wrong. You are talking about what was happening hundreds of years ago, but you are not seeing how hinduism is transforming itself by accepting that cast system is wrong. I have studied in college with all my friends from hundred different casts, but I have eaten with them, played with them and never cared about their cast. Biggest thing is our ability to accept what was wrong in us, and our trying to correct it. Soon we will be free from castism. Now, Hinduism has castism does not mean that Muslims (who you are) are all good. In Islam, its defined that women are like objects for men. Also, its defined to kill innocent ppl if they doesn't agree to follow islam. What a shame. You are trying to hide your flaws behind the cast system of hinduism, but we are atleast accepting our flaws are correcting them.
