My question about larger parasites (larger than microbes), by the way, was not intended to be hairsplitting, but to ask whether you were including the larger parasites amongst those that the organism deals with using the same branches of the immune system. I don't recall taking unfair advantage of any semantic mistakes on your part, but I must admit that if anybody tempted me to do so, you would. Anyway, if you'd care to follow your own protocol requirements and quote us on our unfair tricksiness toward you, perhaps we will be able to address it.
Also, it might help Ardavan work out what on earth you're talking about in criticising his "lesson" if you were to follow your own protocol in doing so. You keep asking everybody else to quote you etc., but you seem to except yourself from that requirement fairly consistently even after it's pointed out to you that you're doing so. With your writing in particular, which tends to go round in circles a bit, being able to see in quotations the exact topic of each critique in a message would probably serve as a useful anchor for us mere mortals.
Cheers!
