samsara bro,

good answer. quite long, phew!!

but there are two thapas - one is magar (indigenous tribe and makes about 7% of Nepal's population) and the other is Chettri thapa (makes 12.5% of population and 15% are bahuns). i hope u know this.

since this guy started this thread, i will give him what he wants. to me chettris and bahuns are similar. these (chettri thapas) imposters join british army saying they are magars. 

more on the way.
