That’s bit of a naïve generalization coming out a person who looks like an anti-reservation bigot. It is already understood that many OBCs (not all) had experiences similar to that of Dalits. Using only one example of a powerful OBC group, that of Yadavs, to characterize thousands of OBCs castes in different regions is oversimplification of a complex problem. Some OBCs are closer to upper castes while some are closer to Dalits. Not all OBCs are the same in all regions of India.
What we need to learn from history is exact opposite of what this author suggests. We have to bravely face the reality, not hide from the truths that continue to haunt us. Caste is a reality that will not go away just because you refuse to look at it. It has stayed with us for over two thousand years, and it will continue to stay for another three hundred years. It is not a simple problem that can be wished away. So, let’s not pretend the problem does not exist. Real problems require real solutions based on real data; and it needs people with guts who can face up to that reality, not cowards who want to pretend the world has become safer just because they refuse to look at the evil in the eye.
