I could point to the Antioch shooter, and weave some bullshit about Black people being dangerous and antisemitic.
That would obviously be dishonest, and intentionally racist.
He was a Black man radicalized by white-supremacist and Nazi content online.
He didn't become a murderer because he was Black. He became a murderer in spite of being Black.
He very clearly wasn't a Black nationalist, because his manifesto was full of very explicit anti-Black racism.
