What us citizens of a wiki use to protect ourselves from HolyWars on the wiki pages when we invoke them.
"Them" being the wars or the shield?
Now that I think about it, there should be a FlameWarShield to go with the HolyWarUmbrella.
A HolyWarUmbrella, of course, is designed to conduct electricity safely to the ground and away from you. This protects you from the angry SmallGods of various programming languages/methodologies.
