I don't know about us having "more expertise"TM, but I've certainly noticed over the years that answers on SFF:SE tend to have a stronger emphasis on in-universe-evidence compared to Movies:SE where there's often a stronger emphasis on real-world-evidence. Based on the comments you've made under the answers you got, it sounds like you were much more keen on the former than the latter, which means that SFF:SE might have been a stronger choice for your question.
If I was answering this one, I would probably have focused on identifying any episode examples where the sensors are used to identify individuals by gender (e.g. demonstrating that trek sensors can or cannot readily distinguish male from female), examples of crewmen referring to a sensor-detected person by their gender (e.g. demonstrating that the crew typically assume someone is male until positively advised otherwise) and evidence from the various factbooks that make reference to how the sensors work.
I'm reasonably sure there are in-universe examples of each that would have allowed me to craft an answer that satisfied my own curiosity on the subject.
As to how to ask it over here, you simply need to avoid it being a cross-site duplicate. Merely ask the question in a slightly different way (for example "Can Trek sensors tell the difference between male and female lifesigns?") and you'll get another set of answers, hopefully to your own satisfaction.
