The FBI has not designated White Supremacy as our greatest threat. It’s designated racially/ethnically motivated violent extremists (RMVE) as our greatest domestic threat. That includes all race-based hate groups; even BLM and white-hating ANTIFA.
According to the FBI: “The greatest threat we face in the homeland is that posed by lone actors radicalized online who look to attack soft targets with easily accessible weapons.”
So, get your facts straight before you hate, Sherlock.
