Caste is not 4 letter word. It is more like a 3 letter word: you talk about it, but with a giggle; everyone does it; with some one close you can talk about it openly - the good, the bad & the ugly aspects of it. Ignorance or denial of it, like that of its 3 letter cousin leads to wrong attitude, confused identity, relationship problems, & exploitation. Caste Education/Literacy is a right of information in a matter that affects us so as to have healthy identity and relationships
