it's not caste, it's nepotism. malnutrition in india is worse than in sub-saharan africa: it's poverty, not caste? incomes in india, per capita, are better than in a majority of african nations. it's the population, not caste? china has a bigger population and lower malnutrition rates. it's democracy of course, not caste.
it's not caste? take a closer look before you rush to defend it. and why do you have to defend it so strongly?
