As an aside, my guess is that we do have a Jihadist or two, certainly on the arabic wiki I would assume. I've often wondered how many CIA agents and etc.. we have as well. They would be very foolish to completely refrain from reviewing or interacting with such a dynamic source of data.
On topic, I think describing wiki-events in hyperbolic terms is stressful and encourages squabbling. It also embarrasses me and makes me think i might have go to the pub instead of edit the wiki, if I want to engage in a rigourous dialogue ;)
Perhaps we could have a lesser version of No Personal Attacks advising against describing an edit war or deletion of ones vanity page a holocaustic genocide, or an arbcom case as a "racial attack" and Lynching (the former I don't know of having occurred, the second refers to a current ARBCOM case ;)

In any event, this is no more "libel" than your own hysterical line about "crusaders and jihadists," which I assume was probably not actually a meant to be interpretted as anybody on Wikipedia actively being members of the 15th century European invasion of the Holy Land or active members of Islamic extremist movements.
