People still consider caste a big issue in every part of Nepal.I am not sure whether it helps them identify themselves or to degrade others.Forget about others parts of Nepal,in Ktm people still call each other 'Jyapu,Kheni,Bhote,Madhise etc'.But people are opening up.I think the current generation is having lots of mixed marriages compared to the previous one. People need to get out of their house,locality and country to know about others custom and traditions.
