it seems to have been pretty successful sexism baiting if that was the original intent. I think it was a really innocuous line of text, I think it upset someone who is particularly sensitive, and Blizzard took the simple step of removing it to placate the original poster, and to douse the flames of angry debate that it seemed to spawn.
honestly I think the line could even have been a placeholder. see Wrynn's 'heeeeeey girl' when the first female Pandas got the Stormwind.
