Read what I wrote, and you might figure out your mistake
Yes, I know you used “they” not “he”, but that’s
no more than semantic wordplay.... it’s a rape trail, “they” are not on trial, “he” is.... If “they” didn’t consent in the context of a rape trial, it could only conceivably mean it is the woman who hadn’t consented.
It follows therefore that proving “beyond reasonable doubt that they had consent” is the same as proving “beyond reasonable doubt that she had given consent to the man”, and unless and until that it is proven, logically the man is guilty.
