There are people who use gender-neutral pronouns and want to be addressed with neutral language. For example, because they are non-binary, that is: neither men nor women. More info on non-binary people can be found at nonbinary.ch.
We'll explain how gender-neutral salutations & pronouns work quite simply here. However, this explanation does not claim to be universally valid. People may want a different way of dealing with things than described here. This explanation is only a tool so that people do not have to explain everything again and again.
There are people for whom "he" or "she" does not fit. They then use gender-neutral or no pronouns. So when we talk about such people, we use gender-neutral language. For example: Alex does not use pronouns. So instead of a pronoun, we would just use the name:
Alex lives in Zurich. I have Alex and we agreed that we'd spend the weekend together at Alex barbecue.
Kai uses the pronoun "dey/those/their.” It goes like this:
Quay has their I brought my bike in for repairs. I have which so I'm borrowing mine until dey to get the bike back.
By the way, it's best if all people include their names and pronouns in their Twitter bio, email signature, business card, etc. Because: You don't see pronouns on a person. This normalizes asking people for their pronouns & trans people don't always have to explain themselves.
That's what people do most of the time:
Alex (no pronouns)
For example, when we address a letter, there are several possibilities:
Good day Alex Mustermensch
We also need gender-neutral alternatives for terms like student, son or daughter, father or mother. We can then, for example, use words like student need or Child, Parent or Parent, Siblings, Roommate, etc.
