Caring more for the plight of people around you than people in far away countries isn't discrimination, it's rational self-interest. I want to see healthy, thriving communities in Baltimore because I live there. Those people are part of my community. They walk alongside me and interact with my family.

The irony is that people in India and China understand this simple dynamic perfectly well. You don't need to explain to the average Indian or Chinese person why they should care more for the plight of their neighbors than that of, say, even poorer people in Africa.
