Don't shoot me cause I got that picture from google. In fact it is the first thing that comes up if you type 'Nepal caste'.

@shiva_linga I don't know about traditionally hindu and non-indigenous but you say janajati have caste hierarchy which is true but one thing I agree with that pyramid is that unlike the 3 communities mentioned, Newari, Madhesi, Khas - the others do not have hierarchy based on varna system, from Brahmin to Dalits, or am I being wrong here? I know Tamangs have different clans and some like Lama are more respected than Ghale for example, but there is no fixed restriction on marriage between a Lama and Ghale primarily on the basis of things like caste, lineage, purity, pollution, and the 'varna'. I mean a rich Lama would never marry a poor Ghale, but if they were of equal setting, the issue of caste would not be a problem, which is different compared to a rich Bahun and a rich Damai in the same situation, or a rich Jyapu vs. a poor Joshi, or between a Paswan and a Kayastha.

And I think we (and by that I mean Pahadi Bahun and Chettri) need to really take a hard look. The moment issues of caste is brought up, we tend to shun it saying those are the things of the past and we are all modern creatures now. We take no time saying we don't need jaatiya rajya and all that crap but hey - we are always the ones who identify ourselves based on our jaat and jaat alone. When asked to identify ourselves, we are the ones who say we are Brahmin. And in a society which has Brahmin, Chettri that society will automatically have a Baisya and Sudra. I know dozens of my own people who are zealously proud of our Bahun heritage (which I get it everyone should be proud of who they are and their heritage), but when that identity comes from an evil institution which has for generations benefited you at the expense of others, what is the point of that high-ho fake proudness?

So spare me this show of your apparent allergy to pictures like that pyramid which just reflects the present condition of our social reality. What we actually have to do is try our best to end this dual hypocrisy.
