His theory said nothing of the kind either when he said or when it was originally advanced by Dr. Willke, head of the NRLC. Both make it explicitly clear they are distinguishing between forcible rape and statutory rape. The notion of enjoyment was not referenced in the slightest. Their theory about pregnancy only applies in a forcible rape, not in a statutory rape where there may be consent from an underage woman.
It is the logical inference. He takes the position that a woman forcibly raped won’t conceive because of the extreme stress. Therefore, if a woman conceives after an alleged rape it must not have been all that stressful for her - ie. she must have enjoyed it.
That is beyond a an awkward sentence. That is a monstrous insult to every woman ever put through this nightmare.
