I’m not so sure we call them our people. Now we are one, but the way we are is different than anyone else in the world, and is not natural. Do Muslims condemn the killing of Muslims? Do Christians mourn the death of their co-religionists?
Are people really personally affected by a stranger’s tragedy? I don’t think so. There are surely feelings of sympathy and “our hearts and prayers are with them” while we munch pop-corn and click on the next news item.
This is magnified when the people we are talking about are oppressed. When someone is being overworked, under-rested, beaten and over-stressed, he has very little time in his hands and room in his heart to feel for others.
