I believe the people of Nepal will build their temples again as it's their right and beliefs. I've studied them and referring to them as " Pagan" is a typical view of others that do not know any better. It just shows how most religions think that their religion is the only true one. That's not the case. If all religions would just get along and see each other as equals, there would be a lot less war and strife in the world.
As I'm not a Christian myself, I believe that the Nepalese people will build their temples and worship as they have for hundreds of years.
