That's probably true, and that's good. However, that doesn't mean that the author's gender doesn't influence the work itself. You are not deliberately opting into skewing the data yourself, but you are still consuming a biased input set.

I don't think that's the case. I think it's just the more value-free observation that "this set of data points is biased." It doesn't state why it is, just that it is. That might be relevant to someone who expects the list to reflect a certain distribution of perspectives.
I think I have the same ratio in my bookshelf. More interesting the subject is for me, less women. For example: I have ~50 computer science books and only one is written by a woman (Sonya E. Keene).
