Wanting to know someone's gender can be reasonable. But... on StackExchange? I can count on a single set of digits the number of times I've personally witnessed someone knowing someone else's gender leading to anything better than a neutral outcome. Doctors factor highly in that list. Then dates. Online people... well, only when it was extremely on-topic. Like a time I saw someone getting advice on 6-point racing harnesses vs. 5-point (re: strap geometry to protect the lower body).
As an example, let's take scicomp.stackexchange.com (computational science). Neither a participant's sex nor their gender is an appropriate topic there, with few exceptions. Is a reasonable policy there to avoid all gendered pronouns when referring to other users, unless there's an on-topic reason? Is using "they" or the user's handle worse than bringing gender into the conversation, when this is clearly off-topic? Monica seems to be negotiating for the option to use gender-neutral language. What are the pitfalls if we mandate it? The language can be a little awkward at first but that's a small molehill to die on.
Personally, I've always found it strange that we collectively broadcast our gender so far and wide. We don't continually mention each other's race, hair color, handedness, or preferred sleeping position on every tenth word, yet we often know someone's gender even before we know their name. Why is it so?
Thoughts? Very curious to hear from others. To be clear I have no problem with someone expressing their sexuality, gender, or other aspects of their individuality. I'm a fairly odd cat myself (particulars are irrelevant) and I relish being able to express myself authentically when it's helpful to some goal. I guess I'm mostly challenging the central role gender plays in our language, and asking whether or not we should change this to allow people more flexibility in what they disclose.
