Social Justice: Caste Away
Your birth as anything (class, caste, race, nationality etc.) or with any trait (skin color etc.) considered to be a characteristic of an inferior human being is not shameful. YOU HAD NO CHOICE IN THAT!
It's those that view and interpret that as such and make you suffer for it who are shameful: THEY HAVE A CHOICE IN THEIR VIEW OF, THEIR ATTITUDE TOWARDS AND THEIR TREATMENT OF YOU!
