Your example is exactly what the US is doing. Faced with a threat of Islamic extremists it wastes resources and alienates people through targeting at airports by race rather than for purely intelligence based reasons. I'm glad you agree this is illogical. I have no problem with intelligence based targeting. I loathe Islamic Extremists and their pathetic world view and unlike you I wouldn't fund them to further foreign policy objectives. But maybe you think targeting skin colour alone is intelligent. Since 9/11 white males going bonkers with big guns have killed far more people in the US than any terrorists. I'm trying to illuminate why instinctively you would reject profiling on this basis, or to say that this is a problem white people need to address. It's quite a simple analogy. Try also to sometimes think of these boards as somewhere we kick ideas around rather than make public policy. You might release less steam from your ears.
