That's not racist, it's true. Slavers
did breed their workers. If anything, the person who offered that explanation is trying to correct the racism of the other guy who apparently wonders why so many sports players are black. Or not, but at least he's aware.
Another true point is that most black Americans today, especially in the South, are descended from slaves. When is the last time you heard a black person with an obviously African last name who wasn't actually an immigrant or refugee? @
Noob616 just mentioned in a post above yours about a black hockey player named Evander Kane. Kane? Kane is an
Irish name. Black people aren't native to Ireland. The name Kane was
given to Evander's ancestors, likely by an Irish slaver named Kane. It's pretty wild when you think about it, that there were so many slaves in this country at one point that most black people you know today are descended from them.
People like LeBron
James, Shaquille
O'Neal and Michael
Jordan don't just happen. Like anybody else their traits are inherited from their parents and when provided a good environment they will stand out. In their cases, size and physical prowess were prominent.
