that sounds good! so, in my understanding
amplusian: genderfluid and/or genderflux
genderstatic: not genderfluid, may be flux
genderstable: not genderflux, may be fluid
suptilian: neither genderfluid nor genderflux
amplusic: orientationfluid and/or orientationflux
orientationstatic: not orientationfluid, may be flux
orientationstable: not orientationflux, may be fluid
suptilic: neither genderfluid nor genderflux
i think that we could coin some new terms for the middle two.
orientationstatic: kymenic
orientationstable: diastimic
genderstatic: kymenian
genderstable: diastimian
terms for genderstatic and orientationstatic come from κύμα, greek for wave. terms for genderstable and orientationstable come from διάστημα, greek for the space (as in intervals).
