I feel like, it's not that they can dismiss step siblings or adoptive siblings but there is some sort of comfort in knowing that they are not blood related. Blood related siblings are harder to accept in yaoi but this is a little more "acceptable" they may know each other from a young age but at least they don't share the same blood
The technical term is ‘pseudoincest’. But why do people feel different whether they’re blood related or not, they’re still brothers that were raised together, and they’re gay so they can’t make babies.
Idk, I think it’s strange when people feel different over step or adoptive relations over biological in same sex relations despite not being able to conceive in either
Because it’s still weird in my opinion, it feels like people can dismiss adoptive or step relations over blood which is sad
