* So we've been through 2 decades' worth of feedback from Fluid Peoples, these people of ours now feeling safe enough for their points to be made anonymously in the public domain.
* In outline, we start by having Genderfluid awareness, including understanding how such were oppressed in LGBT communities in the 80's, 90's and 00's.
Followed by Switches giving a similar account of their oppression in BDSM communities, and Ace Spectrum people talking about Demi and Grey, and Survivors talking about PTSD-induced long-term temporary Aceness (and/or Aroness).
We've also had some people start to mention SAx-Fluidity (Social Anxiety Fluidity), and some are talking of their Million-Labelness to Acategorical transition as a type of Fluidity.
* So, aside from the by now elsewise well-known GenderFluid people,
there is the general
Social Anxiety Fluidity
Kink Fluidity (including Switches)
Survivors in Transit (e.g. Fluidity between being an Avoidant Survivor and being a Confrontational Survivor)
is of this general nature as well.
There are of course some further cases. Any spectral characteristic can manifest itself Fluidly :)
