I think some people confuse wingers of every persuasion with the mentality of the average U.S citizen. Most Americans are compassionate people who go out of their way to help those in need. But rarely are they reported on, for some extremists make for much better headlines.
I would go as far to say that those who seek factual debate and are interested in solutions, rather than arguments, are ignored just the same. So we have to wonder if the few who are indifferent to the plight of those down on their luck are just convenient scapegoats.
