Wow...that's a really idiotic thing to say.
I don't really have a problem with Manny walking/staring/pointing last night, I don't care that Babe Ruth called his shot, and I don't care that the Harlem kids clowned around like that. It's all showboating, it's all equally obnoxious, but it's part of the game, for better or for worse.
Stange thing though. You list all these examples of minorities getting shit on by the media, yet you fail to mention that hardly anyone says a peep about Sosa's hop-step, the Rams' "Bob-N-Weave" from their Super Bowl days (hell, ESPN ran that as much as possible), or Michael Irvin's "first down" gestures. As far as I'm aware, those guys get credit for being showmen, not jerks.
Your argument of racial bias is asinine, as it usually is when folks play that card.
Oh and just so you know, Ralph Wiley is an idiot (no, I didn't read the article you linked...I've read enough of him before).
