"That quote is talking about pregnancy, not the rape itself."
"I'm not defending the legitimacy of using the phrase that way, I'm clarifying that there was no intent to state that the human body "shuts down rape" which is how the quote can often be perceived devoid of context."
1. Is the quote talking about shutting down rape or is it talking about pregnancy from rape?
2. For the person not clued in on the broader discussion, could a reasonable person infer that the quote be about rape and not pregnancy?
Answer those questions and come back to me on what your beef is with providing clarity around the quote.
