There is a rather disturbing subset of the right, the so-called human biodiversity (HBD) believers. The most prominent pundit belonging to the school is Steve Sailer, who most of you probably have heard of. These are the people who believe that blacks, and other groups, are biologically inferior to whites and Asians. They are strong believers in the material in “The Bell Curve” and other similar works. I’m willing to bet many of these wingnut bloggers are believers in HBD, though they may not outwardly admit it.
