By "nigger" do you mean all Black Subsaharan Africans, or just the image of loud thugs that you dislike.
By overfocusing on the worst, you obviously would get a negative impression.
By asking for proof of equalness, you are stupidly assuming people have a set and non-situational comparable value. Chris is a degenerate dumbo, but his ecentricity makes the world laugh, Blockhead is an excellent programmer, but consumed with hatred.
