The really impressive thing is that you can be sure those two would be the first to yell "CULTURAL APPROPRIATION" the moment they saw a white girl with a feather in her hair, but at the same time they're completely ignorant of the culture they're trying to appropriate.
The uncomfortable truth (for them, anyway) is that for a lot of pre-modern cultures a man's masculinity and virility was seen as a gift from the gods, or a representation of one's lifeforce. A man shouldn't squander their seed on another man, or letting it fall to the ground (masturbation). To do so was blasphemy against the gods and people took their gods seriously back then. This also applied to women: their fertility and femininity were their gifts. If a woman refused to attempt to exercise that fertility -- by courting other woman or living alone -- guess what happened? Blasphemy again!
Plus there were the usual societal issues. If you live in a little rural hamlet of 100 people and child mortality rates are upwards of 50%, a single woman not having the usual 8-15 kids could feasily affect the village's whole demographics. And since those societies were usually monogamous they needed a man to help them all those kids so one bender refusing to have kids was also a problem for them.
And those, kids, are just some of the reasons why your gay/tranny ass wouldn't survive five seconds in the "multicultural and multiracial" society you think your ancestors had.
