That’s my problem with Costas’s crusade. He — and the editors of Slate — are simply deciding to be offended about something they don’t need to be.

And though it obviously took on nastier connotations over time and in some contexts, it strains credulity to believe that the team name was intentionally pejorative or that the fans or the ownership see it that way today.
