Yeah, I wasn’t saying that those things cannot be separated, just that they aren’t necessarily.
The label a person uses to describe their gender can be influenced by their presentation, orientation, or the gender roles they want to perform. Someone who says they’re certain gender because they (want to) perform the gender roles associated to that gender isn’t necessarily confusing concepts.
The human gender and attraction experience is so complex that it cannot be put into strict boxes that never mix.
In fact, all of the labels you described here (butch, femme, bear) are all distinct expressions of gender identity, although some of these labels largely overlap with sexuality labels as well, none of them invalidate or have to overlap with gender identity.
My point was that all these labels, apart from being presentations and queer dynamics/roles, are also genders for many people.
Some people are Butch [gender], where butch refers to their expression; other people are butch, and only butch, where butch itself is their gender.
