there might have been mistakes made in the past, but the grievances of past should not be used to break the fabric of the culture which will allow predators to invade and change the nature of the society and divide the nation. Everyone had some role to play in this discrimination, and Brahmins must not be entirely blamed for it though they made their significant contributions, others vetoed it it too. If you want to blame Brahmins and few others entirely for it, it only means that some got away for thousands of years and you were sitting like an ostrich while all this was happening. And now people have a voice relative to ancient times to bring their grievances to the table due to the democratic setup of the nation and it should not be misused to create ripple. Reforms should be done and not divisions. Of course, there should be a opposition voice for comprehensive reforms and that should be the way, which should be encouraged. I actually like this dalit movement, but it gets messy when some use it to convert people and change the nature of society and weaken the voices that vouch for traditions that have something good to offer to humanity other than untouchability and dowry practices etc. There was caste-system in all societies of the world though they followed in different ways.
