The biggest issue I had with female colleagues is not that they were worse than males in any way, but comment like yours. In fact I think on average females are better for the team. I remember I told once told few folks that one female member of the team is bad hire, and the immediate response I got was that I am saying this because she is a female. I might have a bias that I don't know about, but if someone specifically points a single or minority of females to be bad doesn't need to prove they are not sexist.
