Kinda of hard to do that in the dark. Oh and in Bangalore, they are talking about the poorest of the poor. the lowest caste who CAN"T sell to others ans contact with them makes those people outcasts. But other than that you are sadly correct.
I don't where you come from; but I can certainly tell you one thing that one can sell or buy anything in Bangalore irrespective of his or her caste. Unfortunately, Slashdot doesn't allow to mod and reply to the same discussion. So I had to make a tough choice between trolling you down or replying to your post. I've opted for the latter so that at least you can think before you post the next time.
