So men are the only people who comment without revealing their gender? What about trans individuals? Does that mean I can reliably mask my gender by deciding whether or not I mention it in my comments and posts?
And this still doesn't answer what rules you or the men's talk expert you asked use. Anybody can claim they have "a lifetime of experience" in anything they want, but without either an empirical success rate or a set of explicit testable rules, it's all bullshit out of their ass.
>We have a lifetime of experience listening to a man's point of view.
I and a lot of other men have a lifetime of experience listening to women's point of view too, and yet I can find no sane man who claims they can identify gender from text, unless in very special cases.
