History is here to stay. You cannot change it. You can learn from it, use it as a reference from time to time, but it is there. And then there is tradition. Nepal is a majority hindu state. Dashain is our biggest festival. So even if the county become's secular, the tradition stays.
France is probably the most secular country in the world with hardly any religious people. But they celebrate proudly all their religious festivals, because it is their tradition.
You can not call your self Christian, but still get married in a Church. But that is the tradition.

All these left wingers, influenced by leftists bourgeois class of Nepal with links with other countries want to destroy Nepal. The little identity we have left as nepalese, the very many things that helped us to become a proud Nepal today have become subjects of debate today. These people want Nepal to go back to medieval times of baisay-chaubisay rajyas so that India can easily gobble them one by one. People who call them progressistes have been so blind to see this play devised by external forces. Wake up people and unite.
