its a power structure thing it will always be less offensive to kick up than down not saying all whites have more power than all blacks but the white race is more powerful though i think class is more important than race or gender these days id also say historical context matters cracker has not been used the way nigger has i would not say cracker and nigger are equivalent to eachother also if ueclectrical is white then its no different than a black person calling other black people niggers
