Islam churns out white supremacists like universities spit out patriots.
Black muslims have been slaughtering people for the last fifty or more years. The Zebra Killers comes to mind.
“The “Zebra” murders were a string of racially motivated murders and related attacks committed by a small group of Black Muslim serial killers in San Francisco, California, United States from October 1973 to April 1974; they killed at least fifteen people and wounded eight others.” Wikipedia
I read years ago that the Zebra killers may have been responsible for as many as 250 murders.
