I meant things such as background, or what I like. As a woman, I must be straight or full of feminine bias. As a guy, I'm probably anti-feminist, straight, a white knight, etc. I get this from any gender really.

I had a link to a gender guesser once. Basically it would find the ratio of certain words to others (women tend to use more "a" "of" "the"s iirc), but it's probably dependent on American patterns of speech.
