They're very different, BLM don't seek to subjugate white people, they just want action against the disproportional amount of Black Americans who seem to be killed by police. Like the feminists, or the civil rights movement, or the gay rights movements, they scare the shit out of old white men, who lash out. We've seen this all before when minorities speak out, it's tiresomely familiar. Fortunately demographics are wiping out these shitheads fairly quickly.
