HM-m-m-m ... a white guy killing muslims ... perhaps he was just doing the job that other muslims normally do.
Muslim on muslim violence is so common that it rarely makes the news. I am inclined to believe that if the perp was muslim, we would know nothing about this event.
Do you mean like the bombing in Somalia described at the link below that I am sure no one ever heard of?
Muslim on muslim killing is not the anti-white and pro-muslim narrative that the global, leftist media reports.
