I find pronouns other than the basic ones confusing. Online, it's hard enough to tell if someone could be female or male let alone something else and then trying to pick the right pronouns. I can understand wanting to be called by certain things and would try to respect someone wanting to be called "they", but I don't know any pronouns other than the ones in regular real-life use and probably wouldn't remember to call someone by a random foreign (to me) word. :(
