Based on this definition, who would not be indigenous people of Nepal? Do we have a timeline when the migration took palce for those in and out of the scope of that definition?

I don't think it would be wise to compare Native Americans situation with what we have in Nepal, where we lack the time line of migration. Someone interestingly brought up Ne-Muni...

I have no doubt that "Janajati is mauka ma chauka hanne ko Jamat". By that, I absolutely do not mean hard working grass root folks.. I mean those taking advantage of it by appearing to be leading this divisive agenda. United we stand.
