Where do I even begin with this horrible excuse for an argument. While there were racist comments on Twitter (shocking!!) most of the Sherman criticism was for him being selfish and disrespectful, which he was. Sorry. You don't have to care about those things, but it doesn't make it untrue.
The Erin Andrews tweet is nothing more than a joke about how she was scared at a man yelling at her unexpectedly for no reason. Bring race into that discussion is only possible by making blanket assumptions about the author and her motives with absolutely no evidence to back it up.
But the most comical part of this article was the comparisons to other supposed instances of racism against "the conquering negro." While yes, there are racists, most people disliked Kanye's "genius" comment because of how arrogant it was, not because he is black. People disliked Barry Bonds because he was a cheater, a bad teammate, and arrogant to the point of being insufferable, not because he is black. (Most people during Barry Bonds's race to 756 spent time lauding Hank Aaron and his "true" home run record. Last time I checked, he's black too.) Joe Louis did live in a racist society, but that's ancient history at this point, I'm guessing very few people who criticized Sherman were even alive to be racist towards Louis. There's no good reason to lump together racism towards Louis with the Sherman criticism.
My point is not to say that there was no racist behavior towards Sherman, obviously there was. But this article is irresponsible, and bordering on offensive itself, by implying that all criticism of Sherman is racially motivated. That just isn't true.
