Religion does not have a monopoly over morality or ethics. In other words, you don't have to be religious or even be associated with a religion to be a moral or ethical person.
Many societies exist in the world which are considerably less religious than Nepal but, as far as I am concerned, are considerably more moral and ethical.
If the Gods discriminate, why can't -- or even shouldn't -- the humans as well?! If the Hindu Gods themselves discriminate against some humans (at least Dalits) the way at least some Hindus believe they do, what’s wrong with humans discriminating against the same humans?! After all, who better to follow than the Gods?! Right?
Nepalis on average are a closed and inward looking people. And because of that, when the proverbial mirror is held in front of them, offended, disappointed, or not liking what is reflected back, they generally shatter the mirror. In this blog post, I document one such example from Twitter.
