@naln1 It's a shitshow, basically. There's hen/hun that some people use, but that a lot of other people have trouble with (somehow singular use of conventionally plural pronouns doesn't quite 'feel' right in Dutch). There's also 'die', for which there's some arguments: https://langzaldieleven.nl/ -- but it doesn't seem to be very widely adopted among queer folks at least.
Personally, I tend to use 'die' unless otherwise specified, but honestly none of the options are great... (and that's not even going into crap like gendered job description names :/)
@naln1 Yeah, my impression is that that's the safest bet for now. Hen/hun definitely seems to be more preferred as specified non-binary pronouns, but I've never really encountered anyone either offended *or* confused by my use of 'die' as a default neutral pronoun - even if others don't really use it.
@naln1 (It's all a bit hard to say even as a queer person in NL, because NL is pretty... behind on the whole gender thing, culturally speaking)
