The headline is obviously a bit much. The casting of dark-skinned actresses of Indian-origin really isn’t going to change the norms of the Indian subcontinent, or the whole of Asia. But it’s an interesting window on aesthetic standards and cultural creation. Indians who I bring up this issue with routinely suggest “well, you don’t have ugly people in American films.” The implication for many people of subcontinental origin is that dark skin is ipso facto ugly (and in Asia more generally). This seems the ground truth and the rest is just commentary.
