So as as a 3rd generation Irish-American who grew up poor (food stamps and government cheese poor, not quite on welfare poor) my life has been defined by those who cheated sharecroppers and infected Native Americans with small pox? Neither your cartoon nor your explanation of power structures apply to the circumstances under which I came to adulthood, but I'm supposed to feel guilt over my "white privilege?" As most people try to do, I have improved my circumstances in life over that of my parents and am trying to do the same for my children. Haves and have nots are not defined by skin color. Humor being okay if it pokes at a position of power that can stand to be taken down a few pegs, but not okay if it pokes fun at those in a lesser position is hypocracy. Climb down off your high horse before you get a nosebleed.
No, see, that's the thing, you can't take this personally. White privilige has naught to do with work ethic. How long will it take to undo generataions of societal codes and laws, which were overturned in the 60s - by law - not by society at large - that discriminated against American minorities? It's not up to you unfortunately.
