I actually don't think that it's about who can make the criticism, I think it's more about what the criticism can be. A woman really isn't any freer than a man to make a sweeping generalization that is unfavorable to women, especially if it's attributed partially in biology. Interestingly, you really are largely free to do this in reverse, as we see (admittedly in a fairly mild form) from this article. Though be careful here - what seems like a compliment can in fact be very condescending.
