Ok here is a problem now ,If we you do incourage intercaste marriages ,then we will loose the whole cultural thing.most of people don't know there own langauges etc. well if you don't they social cutural descrimination and hatred is not going to go away.Isn't there a middle way out.btw ,in couple of generation we (castes) will loose our cultural backaground and last name will remain only last name -.nothing more than that.How can you save your culture and avoid hate.
