The federalist has a great article specifically about the Atlanta Braves but more generally about the ridiculous name changes.
"Piece by piece the country, the architecture of its ideology, the bones of its buttresses are being stripped away and replaced with mindless bromides. There is nothing offensive about naming a baseball team the Braves in honor of American Indians. You don’t name your team after something you hate or deride. Nobody in Brooklyn would name his team The Queens."
