The number of white supremacists known to the FBI is 15,000 of which half, are currently serving time in a state prison. They're irrelevant and controlled, merely a boogy man for the powers that be, to spread fear and hate amongst the populace.
Regarding BLM......I see BLM as a negative force for black people and for all of us as a whole. They're promoting victim mentality plantations - it keeps Democrats in their jobs!
BLM does not promote positivity and responsibility for one's own actions, otherwise we would not have seen so much violence and wanton destruction of property in the cities. They're inciting hatred and poisoning the minds of young people with their chanting, "pigs in a blanket, fry them like bacon" and "what do we want, dead cops, when do we want it, now" . I'm pretty sure, that the then president, Obama never once publicly called out BLM for their incitement, not even, after the murders of the Cops. No news media furore there, nothing whatsoever. In fact, even after the murders of the cops, Obama invited and held talks with the BLM leaders at the White House!
BLM is a collectivist, hive mentality cult that responds with racism towards any black person that disagrees with their claim, that they're "the voice" of black people.
Antifa and BLM are both fudging useless to everyone but those that want to spread discord.
