I'm non-binary. My English pronouns are they/them/.... In general I prefer gender neutral pronouns, but if your language doesn't support them, ~~you may use both binary pronouns~~ you should really consider recompiling your language with extended support for pronouns.
I do a lot of things with train data, such as [FahrplanDatenGarten](https://github.com/FahrplanDatenGarten/FahrplanDatenGarten) and [pyhafas](https://github.com/FahrplanDatenGarten/pyhafas).
