I'll just play devil's advocate here...this comes from the above link someone gave me and I don't know how accurate it is.
Two white supremacists killed a husband and wife because the husband was a sex offender (7/21/2013) Jonesville, South Carolina (2 deaths)

Anti-government survivalist extremist killed 3 at Planned Parenthood clinic including a responding police officer (11/27/2015) Colorado Springs, Colorado(3 deaths)
There's no evidence the Oregon shooting was carried out by a white supremacist. He was black for one.
The Las Vegas attack was carried out by formerly right wing types, who later became left-wing types (which is why they left the Bundy ranch). They were pro-illegal immigration and likened their victims (cops) to "Nazis". Wouldn't that be left-wing?
Anyway, you can't match the Jihadists death toll, but that's only because of 9/11 and fluke 49 deaths at Pulse.
