HAHAHAHA You are too nice trying to reason with him.
My usual reply is "I apologize for having a real life outside of this game and for being out of touch with pre-pubescent mentality of whining."
Then I thank them for th egood laugh. Any other attempt by them to do anything else I reply with a "lol" and nothing else. It annoys the crap out of them even more. If I'm ina good mood I'll leave the pre-pubescent part out. if I feel nasty then I tell them they are the reason I believe in abortion.
People like that are the kind that also cut you off on the road and flip you off. Just take comfort in the fact that what goes around comes around. The fact he replied and gets bent out of shape is because he knows he was whining like a bitch.
BTW .. it is almost tempting to make a toon on his server and send him a note lol If you have time
