There is reason to believe that strict right-wing ideology might appeal to those who have trouble grasping the complexity of the world. Science has confirmed what some of us long suspected but were (sometimes) too polite to say: People with racist and rabid right-wing views are stupid. A new study finds that children with low intelligence grow into Tea Party-ish adults who want black, gay and other troubling types to just go away, please. Stupid people may not like the findings and protest with signs like this. As always, we wish them better spelling.
