I looked into the SPLC body count, to see how many actual killings, besides the Breivik incident, were involved. To remind you, the claim I discuss below is
"In the past five years alone, Stormfront members have murdered close to 100 people."
77 are Breivik's, and I only count sixteen non-Breivik murders since 2008 in their narrative, for a total of 93. These include
Oh, and there's Luca Magnotta, a Canadian. He was a hate criminal, since he dismembered a Chinese immigrant, but does he count? It happened in Canada. Heidi Beirich was quoted as saying “more people have been killed domestically by radical right extremists than Islamic extremist..." Canada is not "domestically".
See White Homicide Worldwide, By Heidi Beirich (PDF), which fails to include a helpful chart.
The only two possible actual hate crimes on that list are Richard Poplawski, who shot three police after his mother dialed 911 over an argument, and the guy who shot up the Sikh Temple, killing six. Of all of them, the Sikh Temple is the only one that's actually a hate crime.
