I did. That section is primarily discussing analysing the pronouns used to find a gender of the target, or exploit word based genders in those languages (French in one instance) that support it. Other examples were a selective study on Twitter, where the experimenters don't even know the true gender, or even humanity, of the user. The author of the section seems to disclaim the entire idea, somewhat (as it probably should be). I was looking for something that could hold up to the claim that individuals of the same gender do, in fact, have common speech patterns. For example, "this pattern has only been observed with women", and, "this pattern has only been seen with men".
