When was the last time you heard a black person call a white person a Cracka or a Cracker?
Hardly never if ever.
Have you heard a group of black people at a sports event call white players Crackas or Crackers or Crackheads or Crackerjacks?
No you haven't.
Nope.
Don't get me wrong, some black people do call a Cracker a Cracka but it is an extremely small number who do, and those who do, say it extremely rarely.
This is why you do not hear it or see it in public.
Why?
Because they say it all the time around each other, especially in the home.
And this is why it comes out easy and often in public.
It is a deep-seated oration they occupy themselves with in order to pacify themselves.
Black people ain't got time for that shit. We actually don't concern ourselves with cracka crackers nowhere near as much as white folks are all the time focused on black folks.
Most white folks exemplify the worse side of being an animal.
In other words, any cracka cracker who says nigger, even once in public, has said it frequently and recently in private. It is never a slip or a mistake or anger-induced or alcohol-induced.
It's deep-seated from a humongous monstrous rotten tumorous cancerous terminally ill inhumane spirit from which the desire to spew self-hate cannot be depleted or contained because it comes from an internal volcano under pressure that can't free itself of itself. The same place that produces angels and demons that only the alignment of star constellations can change.
