1- Race is insignificant in determining the potential of any individual.
2- Ancestral pride is taking credit for shit that other people did before you even existed.
1 + 2 = Anyone going on about their race, other people's race, Nazi shit, or whatever, is a special edition elite dumbass of the first order, and whether or not these people can handle their instruments is a moot point if they involve any of this in their music.
Look, I put up my mother going on about my pals, spics, wops, and what have you when I was growing up. I have no interest in hearing this bullshit from anyone, at any time, and certainly not in something (music) that I consider important and powerful.
