I suspect the underlying theme is the gynocentric dehumanization of men as mechanical beings engaged in mechanical actions.
It would follow reasonably from such beliefs that sexual injury cannot occur to a male minor based on the mechanization of his sexuality.
Sex for a female is of course psychological and not mechanical which subjects her to injury.
In the case of Homolka the same would ring true. She as a woman cannot experience a "mechanical" reality but rather experiences a psychological reality. Therefore she cannot be held responsible for the "mechanical" murder of her own sister.
These are cultural identities projected onto the genders and emanating from gynocentric patterns of ideation. It is no different for the fighters and in Gavins terms it' would be better to monetize the mechanical male and make a profit.
The point that is missed is that sex much like murder or a violent fist fight is psychological not mechanical. Therein lies the enduring injury, wholly psychological.
