Thanks for your inputs guys! U guys have mighty points....In my view, I think to some extent education is the key to lock that ignorance.....it helps to change the society quite a bit. At the same time "bhinazu" brought out a disparate idea. It's very interesting. I have seen people putting their last name in a title like "kavi", "sapana" etc.... just random words that people like. But it might take some time to apply too. It might take a long time to change this system in our society but I can see our young generation have a different perspective on this than the previous generation. But some of the educated people who have so called " high caste", they don't want to change the system because they are considered powerful, intelligent until they have their last name. As a result we young people suffer quite a bit..... not only we can't marry with our choice of person but our choices are limited to within our caste (and even in a one caste let's say newar.. there are several levels too.....which is ridiculous in this century. We get one life to live and we can't even choose our life partner phew! The discrimination of the so called "low caste" people is intolerable....everywhere like work, society, social gatherings etc. Lower caste people are getting poorer and poorer whereas upper caste people are richer and richer. Hopefully next generation people will be more educated and smarter....but we have start that process from now.....let's brainstrom some ideas...
