People are even more unmoved by accurate pictures painted by statistics than they are of "minorities living on the edge". That's the problem here. The ACLU is trying to relate to people on a human level so that they can build some support. So what if they end up producing something very biased? Is this a scientific paper in peer review? I think most people are aware of the fact that the ACLU is a civil liberties advocacy organization and that this naturally biases towards the left wing.
