At the risk of sounding twice as stupid, I think there is merit in thinking about the terrorism conundrum in biological terms. I liked the squeezing-the-puss-out-of-the-boil analogy. LOL
I think you're right. If you talk about the immune system accurately, there is an analogy. But if you make it sound like the immune system "dialogues" with pathogens rather than destroying them (like this guy does), you sound real dumb.
