With democratization in Nepal comes secularization. Nepal has been a Hindu monarchy for close to 250 years:

Since it was unified by King Prithvi Narayan Shah in 1768, Nepal has been ruled by a Hindu dynasty. Its kings have bound themselves into a litany of Hindu rituals. [Link]

This man has no connection to the protests, I just liked his photo.

However, soon it will be neither if the Nepalese parliament has its way. These changes have more than mere symbolic significance - they affect the balance of power within the country. For example, control of the military will no longer be reserved for Hindus:
the army - hitherto ruled by top Hindu castes - will now be “inclusive and national” in character. [Link]

Official broadcasts will have to be more even handed between faiths:

the state broadcaster gives … [Buddhism] 10 minutes a week compared with three-and-a-half hours for Hinduism. [Link]

And more non-Hindu houses of worship will be built:

Pastor KB Rokaya heads a church which meets in a private flat because churches are not allowed to register with the authorities. [Link]

However, not everybody is pleased with these changes. The head of Shiv Sena Nepal said, at a recent rally:

“Nepal is a Hindu country,” he says. “It is the playground of God and a very holy country. If Nepal is not a Hindu kingdom then there is no Nepal. We are entering into a holy war,” [Link]

One of the demonstrators at this rally promises worse:

“In secularism it will be very difficult for … [religious minorities]. The churches will be destroyed, the mosques will be destroyed. The people who are very much [of a] religious mind, they will spontaneously blow up these churches and mosques. The fight between the religious communities… is not going to stop. It has been ignited…” [Link]

At this point, it is too early to tell if this is the usual windbaggery by people resistant to change. There have only been a few dozen protestors at these rallies thus far. The question is whether his movement will pick up steam or lose wind or further mix metaphors as time goes on.
