Black folks have never been equal to white folks in this country: economically, sociologically, politically, educationally, etc. White people calling us ****** or anything else derogatory was UNPROVOKED by a group of people that brought us here in chains, became rich off of us, whipped, mutilated, killed, lynched, raped, culturally robbed, severely psychologically damaged us and deprived us of any upward mobility for HUNDREDS of years.
The negative effects of such multi-generational abuse have not just magically gone away. They still exist in a very real way. A band-aid does not heal a shotgun wound.
When we, a people still living under a system of psychological slavery and white supremacy - refer to white people as CAC and so on, it is a subconscious and sometimes conscious REACTION to oppression. In some cases it may be random and it may be rude, and to a degree it may be prejudiced - but it is not RACIST, as we lack the power to commit racism against white people on any tangible, societal level.
Thus, "******" and "cracka" do not hold equal weight.
Let's say for example, on one side of things, a Nation of Islam leader was to call white folks, "white trash", "cracka" etc. - and on the other side a Ku Klux Klan grand wizard referred to all Blacks as coons, it could not be said that BOTH the Nation and the Klan are racist, terrorist organizations. The Klan has a long history of countless rapes, lynching, murders and other violent crimes throughout its history - supported at times by even the highest levels of government. The same cannot be said for the Nation. The two are not the same on any level - though some whites have tried to equate the two (a backhanded attempt to avoid culpability for their racism).
