It's pathetic that a black person need only invoke slavery to win a debate these days. In fact, they don't even need to do that, as shown in the OP's meme! Now it's just invoking the idea that something might maybe sort of almost be kind of in a round-about-way like slavery!
That a person being paid millions of dollars to play a sport could, in any way, be considered slavery, speaks volumes about the insipid, vapid, pernicious insanity that has infected America. Insanity, it must be said, that has been spewed, primarily, from Progressives and their Socialist/Communist ilk.
Also... who gives a crap what the Hell Calvin thinks?! His main contribution to society was gangster rap... music that told kids like me when I was growing up that it was cool to drink, smoke, do drugs, hit women and commit crime in abundance. Now everyone holds their breath for the next pearl of wisdom to drop out of that idiot's face... stunning!
