The writers don't use role-playing game stats or the stats on the back of the trading cards to define the strengths or abilities of their characters. They let Storm win if they feel like having her win. Flaming occurs when two people resort to highly insulting namecalling. If it continues with more than two posters or two posts, it's probably become a flamewar. Flamewars are bad.
Posters end up taking sides, and the whole thing gets really messy and the posts get really huge.
If someone is really being an annoying jerk, don't insult him in public. People are much more willing to follow your example if you're nice about it. And remember, some people haven't read the FAQ or don't know which threads to avoid. Don't chew them out. Instead, e-mail a polite reply and tell that person where to look for the correct info.
