What is '2S' of 2SLGBTQIA+?

Well....it means two-spirits.

In the American Indian gender business....they stood up and said they have a belief where you could be male and female....at the SAME time.

The idea that LGBTQIA will go past the 2SLGBTQIA-plus?  

I would argue within a year.....at least twenty additional genders will be added....making LGBTQ impossible to keep 'balanced'.

You will have witches with different genders.....Haitian witch doctors with various genders....ghost-gender....cartoon character gender, and maybe even BDSM added for the really freaky bondage folks as a gender (not a fetish).
