If you are not transgender, and you are in charge of software decisions and demographic information, here is a free tip:

Unless it is critically necessary to the function of your software, the best thing you can do to protect trans people at this time is to **not collect any gender information.**

There are almost zero cases where gender is relevant to the function of a piece of software. If your knee-jerk reaction is that your software does need it, please examine if that's really true, or if you just assumed.

Many non-transgender people think gender is a way to distinguish individuals. I search demographic records professionally. That isn't an adequate way to distinguish people from each other, it provides very little information. Many also feel gender is just a basic trait everything should ask about. Please recall that the safest approach to handling any sensitive data is to not store it at all.

If you have questions about something I've said here, please ask. I will answer your questions and we can talk about how to meet your goals.
