@j @Deplorable_Degenerate @adequate @graf @lanodan @p @shadowferret @zerosum the arrangement existed but

1. it was not in every tribe
2. it was different in every tribe it was in
3. it was accepted more or accepted less depending on the time period, I am not well versed but when I looked I found evidence that made it seem like it was never considered ideal for the people involved
4. the concept that unifies all these different things is a modern academic construct not a thing that existed
5. I'm not clear on how many drops of native blood you have to have in your veins before you genetically are capable of being two-spirit, it's quite amazing actually, a gender that only certain ethnicities can have or if you say you are it you are racist
