It means anyone who fights for
equal opportunity for black people. Often associated with the civil rights movement and started in the 1860s. During reconstruction, these activists started work. Most black activists are peaceful people. Martin Luther King Jr was one. He was kickass. Unfortunate ly some people associate black activists with
Jesse Jackson and his kind. They say that black activist means a black first, whitey
blamer. It is a wrong notion. Most blacks in the US tolerate white people. Inter racial marriages and etiquette are shown towards white people. So do not say that black activist means a reverse racist. Very few of the black activists are vile folks.
