Instead of shouting your individual perceptions as History, try to answer these questions with honesty.
1. If a particular cast is in power, does majority of people from that cast are benifited ? (Not asking about close circle of people who are directly benifited). If you think yes, analyze history of independent India.
2. When you earn revenues and pay taxes, do you do it as an individual (maybe couple) OR as a particular cast ? Then what is meant by benifits for a cast ?
3. Can you prove without exceptions that Brahmin/Kshatriya/Vaishya/Others did fight OR did not fight against Mugals OR British ?
4. If you cannot eliminate cast (even after changing religion), how about accepting it in it's original form ? I'm an IT consultant that makes me 'Others' and my brother in army becomes a Kshtriya irrespective of cast of our parents. The difference here is no one cast is superior to other. Also, it's dynamic based upon what I DO and not what others do.
5. Do you understand CAST as in Classification ? How many classifications you know based on Race, Region, Religion, Sex, Birth, Abilities, Skills ...etc ? Do You think taking care of one will eliminiate the problem ?
A Society that can take advantage of diverse skills of individuals becomes super power. Others are called Third World countries lacking pure drinking water & air BUT fighting internaly based on classes.
