While, for the hill so-called high caste Hindus, Dassain is the biggest religious festival, for many others, it--along with a lot of the other things--is a symbol of suppression and oppression their ancestors suffered from. So, if, as a high caste, your sentiments are hurt by protests against it, I invite you to reflect and imagine how much and how long the sentiments of others and their ancestors must have been hurt by the suppression of, for example, their festivals.
