'Two spirit' is a term invented in 1983, the original term was 'berdaches'.<quoted text>
It depended on which group, but usually 3 and some had 4. I use 'men' and 'women' to denote gender and 'male' and 'female' to denote sex.
Generally, men were hunters and warriors. They ranged further from the group than women. Women raised children and prepared food. Each wore a gender appropriate clothing.
If a male wore the woman's dress and took up woman's work, the male became known as a "two-spirit" person or, in this case, a "womanly man." They basically took up the women's gender and had some magical/medicinal roles (like foretelling the future or dealing with spirits or whatever).
In some groups, females could likewise take up the man's role, wearing men's clothing and hunting, being a warrior.
Their marriage system is based on gender, not sex. So a man could marry a woman or a womanly man. A womanly man could not marry a woman or another womanly man. A manly woman (in the warrior role) could marry a woman, but not a man or a womanly man.
So their understanding of sex, gender and sexuality differs from ours quite a bit. These Christians never get that, b/c they "know" they have the "right" system - and everyone else is a "failed" version of them. So they totally ignore the role culture plays in how people behave - especially in why religious people honestly experience their religion as real.
Yet all believers live in a subjective reality that is based on their religion; all religions are both subjectively real - and therefore "true" in a sense - and human constructed.
Here, we are attacking that subjective reality and we are treated to a wonderful display of egotistical, arrogant and, more than anything, desperate defense of it.
Thanks for asking an interesting question!
I've read the original accounts.
They were basically transgendered Indians who were most often horrible treated and abused by their tribe.
The sexual birth defects of LGBT are found in all cultures.
