How about if we keep it simple? There’s sex without consent. That’s rape, period. It’s not somehow ameliorated if the target is drunk, unconscious, too young to know better, or if you were so kind as to not beat them up, tie them up, or kill them during the act.
It’s also still rape even if you intimidate the victim into silence, get social collusion to shame the victim, or otherwise suppress the evidence that you did it.
If you force someone to eat shit, it doesn’t matter if you put sugar sprinkles on it, or worse, if you put ground glass on a different piece of shit and try to excuse yourself because you didn’t make them eat that.
