Yeah, the leftists don't like talking about this part of history

Or anyone else talking about it.  Doesn't fit the Preferred Narrative™, y'know.
Chinn was a black man in Canton, Mississippi, who in the 1960s owned a farm, a rhythm and blues nightclub, a bootlegging operation, and a large collection of pistols, rifles, and shotguns with which he threatened local Klansmen and police when they attempted to encroach on his businesses or intimidate civil rights activists working to desegregate Canton and register black residents to vote. After one confrontation, in which a pistol-packing Chinn forced the notoriously racist and brutal local sheriff to stand down inside the county courthouse during a hearing for a civil rights worker, the lawman admitted, "There are only two bad sons of bitches in this county: me and that nigger C.O. Chinn."

Although the Congress of Racial Equality (CORE) and the Student Nonviolent Coordinating Committee (SNCC) were formally committed to nonviolence, when their volunteers showed up in Canton they happily received protection from Chinn and the militia of armed black men he managed. "Every white man in that town knew you didn't fuck with C.O. Chinn," remembered a CORE activist. "He'd kick your natural ass." Consequently, Chinn's Club Desire offered a safe haven for black performers such as B.B. King, James Brown, Hank Ballard and the Midnighters, and the Platters; illegal liquor flowed freely in the county; and, unlike their comrades in much of Mississippi, CORE and SNCC activists in Canton were able to register thousands of black voters with virtual impunity from segregationist violence.
