I'm struggling to figure out what you're arguing here. Are you saying that a majority of professional athletes hold prejudices because a majority of humans do? If that's your point then yes sure in the grand abstract scheme of things I suppose we all have our issues.Routine stories or exposures of true colors on social media?
It’s not something specific to the NBA. Most professional athletes aren’t the superheroes they’re made out to be.
That's vastly different than saying the majority or NBA players harbor prejudices worse than quoting an antisemetic rap lyric, though. I have no idea where you're getting that from.
I don't think LeBron is anti-Semitic. I think he said something stupid and doesn't get it. I'm more disappointed with his half assed fake apology than with the Instagram post itself. It was an opportunity blown by LeBron and his team, as well as ESPN and the NBA. In a time of rising anti-Semitism, they could have used this is a very valuable teaching moment. It could have been a moment to discuss why it's offensive. Instead it was dismissed with a "if you think it was offensive".
