As for that other video--I'm only saying it's not proof because they did play rape fantasy games apparently without a safeword. How can the camera tell real rape from rape fantasy?
Even the husband testified that she said "no". I don't care how many scenarios you concoct to attempt to excuse his rape of her, there is no
genuinely consensual BSDM relationship in the world wherein the dominant partner makes that sort of "mistake", and if s/he does, it is rape. For you to keep insisting otherwise indicates that it is you who really does not understand the dynamics of BSDM.
