Sorry, it seems really obvious to me and I have heard it said before, so didn't feel I needed to spell it out: Female authors must be better than most to have any shot at getting published. So, women authors who do get published tend to be better authors than most male authors.

You aren't required to care. Whether or not you care is on you, but if you want quality writing, there is evidence that due to the fact that women are discriminated against, IF they manage to get published, their writing will be of unusually high quality.
