>>81809151 (OP)it has little to do with wmaf being common
it has to do with two elements
1/ AF are attractive
2/ WM are stronger than AM
3/ therefore WM protect AF, seeing them as potential breeding vessels
but see, that's the nuance: maybe they're not into AM personally
but they will still protect them as potential breeders for their own tribe
it's the individual to group jump you're missing here
there are gradations between alien - monster - animal - stranger you would never fuck - stranger you could fuck - stranger you could breed - stranger you would love to fuck - stranger you would love to breed
you might feel like protecting a stranger you would never fuck, and mate guarding a stranger you would fuck but not breed
whatever i know my point is hard to make here
