For me the word nigger evokes a primal hate of niggers and all they are.
It encompassess all the negatives of niggers, from around the world into one powerful word. It gives me good feeling to see its impact on the groids world wide and in person. To see the flash of anger in its eyes, then the realization that they are in fact niggers is just to sweet.
If a new word comes along with more power bring it.
