cant we alltogether scrap the categorisation itself in all forms and ways. the divide then will cease to exist. for example:dont fill up the caste column at all when u are admitting ur child in the school...by the time the child grows up to be a thinking human being he/she'll understand why you did so. the caste column in the form will loose its relevance and then will be scrapped from the admission form. let us all evolve this new thought.
