I think that both sides of the argument are being kind of rude and insulting each other's intelligence; I really can't see this as an issue to be overly concerned with.
As a DM, I run all kinds of female NPCs and no one cares. I also allow female PCs and/or cohorts, which isn't a problem. My players are mature enough (well, in THIS instance at least) to have no problems playing a female character. I don't think any of them has gender issues, and certainly no one plays stereotypes or bimbos. A player of mine just stated that certain character concepts just naturally lend themselves to female characters, just as certain roles in movies also lend themselves to female characters. 
As a general rule, I really don't play female PCs, but this is likely due to the fact that the concepts I create and find fun to play don't lend themselves to females. As long as your players are mature enough, I wouldn't see why not. However, since this is your game, and you are responsible only to yourself and your players for creating a fun game, it really doesn't matter what people on EN World think. If a female PC would detract from the enjoyment of your hobby, don't allow it.
