The oppressor castes who emigrated to US & other developed countries have happily enjoyed & continue to enjoy affirmative action in these countries while vociferously protesting against affirmative action for oppressed castes in India.
The violence, name-calling, insults, and often boycott of oppressed caste people who have benefited in even the smallest way from affirmative action in India has to be seen to be believed.
The amount of hate oppressor castes have for oppressed castes is truly scary. It is completely misguided, because their rights are not being taken away by affirmative action. Yet their hate is vitriolic, violent, and vindictive. But because 99% of those in positions of power in bureaucracy, police, state admins, and the govt are from oppressor castes, we rarely see justice being done in cases of caste atrocities.
