Over moderation is not the cause of flame wars. people's general personilities are. Take Buffalo and me. Neither one of reacts well to hard critcism directed more to at us than at the argument. He also had a knack weather intentional or not of hitting me in places I reacted really badly to( the reading comprehension comments for example( I have been reading at an adult level since like the fifth grade. and scored in the 97% or higher on reading comp on tests)). Rather than blame the mods I would suggest you look inward find out the places you react badly are and learn to deal with them.
