However it came about, Trek's racial toerance message is a powerful one - and it's one that Star Trek '09 encapulates better than any Star Trek has before! There is more (human) racial diversity in this movie than any prior Star Trek one. Look around on Earth, on the Kelvin, at Starfleet Academy, and on the Enterprise.
Case in point: Captain Robau. A Middle-Eastern guy commanding a Federation starship.
Hell - even members of Nero's Romulan crew were given assorted lumps and bumps, indicating Romulan racial diversity.
