Casteist policies are so deeply engraved in our blood, I can show casteism to you everywhere: From Law and Justice (which is above all) to picking a hardware engineer for my colleagues new office ... I have seen it everywhere.
Will it ever go ??? I don't think so. Because India may be a secular country, but its people have a very communal thought process. Sometimes, I feel it is better if each religion is a different nation. At least, people will not discriminate on the basis of caste.
