This claim is pretty easily testable, just by studying people with different sexual orientations.
Not testable that particular way (because I’d expect mindware differences between gay men and straight men to be non-negligible compared to those between straight men and straight women), but only considering people one wouldn’t even consider having sex/romance with. Can (straight) men understand their grandfathers better than their grandmothers, for example, or male politicians better than female politicians?
