These things can only be changed if we educated people start taking initiatives. For example, If your parents want to find a girl for you, you better ask them to start looking for someone outside your caste. And why not break caste barier if it is good for society, humankind and also a wider & varied Gene pool that will help in having Healthier Progeny? In case of our parents, it is difficult to go against the social norms because our society is so much crippled with these deformities that they are bound to be that way. This virus of our society has evolved so much for centuries down to our grand parents and parents that it really needs serious treatment. We all need to take it personally when our parents even want to thrust their ideas of caste system on us. My parents pray for hours everyday, but now they also agree that whatever they were taught to beleive is absolute nonsense. I sometimes feel pround when our neighbors come to my parents to talk about someones kid who elopes away in a different caste and gets a good lesson from my parents. That is how we can change Nepali society.
