Lisa. First of all, I think this discussion should be in the HUMAN-rights section, not the CIVIL-rights. Reason: the broad subject-matter is the tendency of people with strong *tribal* loyalties to dismiss other *tribes* as sub-human. "Tribes" in this context can cover different colours, religions, cultures, social classes, nations, and ethnicities. De-humanizing members of different groups permits tribal loyalists to treat sub-humans like animals.
We see this tendency throughout history, and it is actually no more or less common today than it has ever been. It allows Westerners to allow their nations to slaughter today's Arabs, Africans**, Moslems, etc, either actively by bombs and drones or passively by drownings from flimsy boats in the sea. I say "Westerners" because we on this forum are Westerners; we are (generally speaking) neither better not worse than the members of any other culture. No more morally advanced, that's for sure!
** and their descendants...
