Maybe they're just not effective enough. Right-wingers don't hurt anybody. Leftists have to tar their own side in order to claim there's any violence at all (Ted famously wrote "my fellow leftists"). The FBI has to claim non-whites are whites in order to keep crime statistics up.

Aligning with BLM can't work: they are fake, their ideals are fake, their actions are fake, their accusations are fake.

We can't be Rockwell attending a Malcom X speech, because up at the pulpit is Moshe waiting to amplify his kvetch any time he spots a goy.
