Right-Wing Terrorists:

After the murders in Norway, it's worth considering that here in the U.S. we are more likely to suffer from right-wing terrorists than from the left or Muslims. A recent New York Times' article points out that "(t)he Hutaree, an extremist Christian militia in Michigan accused last year of plotting to kill police officers and planting bombs at their funerals, had an arsenal of weapons larger than all the Muslim plotters charged in the United States since the Sept. 11 attacks combined."

The Norway murderer evidently fueled his hatred with right-wing American blogs.
