Geezus, now card games are being ruined by racial narrative, too.
I and many other people grew up playing Spades, and this is the first whiff of any such historical rewriting that I've encountered (though I shouldn't be surprised). I have no doubt that blacks as a group developed an affinity for the game -- but this piece tries to claim what is otherwise a unifying game is really all about black history. This is right up there with last year's "Police were invented to hunt escaped slaves".
Wikipedia is no ultimate source, but even there the history relates it to other, similar games, and reinforces that it was made very popular by GIs during WWII.
