Can somebody help me with an argument about football?

well, my friend is from scotland and we both support newcastle! i've been to most newcastle games last season (home and away) plus im traveling from liverpool. Well anyway, he keeps posting stuff on facebook like ***** england and how much he hates england (because he is scottish) and i tell him why support an english club newcastle and go to the home games every week and say stuff about england? then he just replays the only place he likes in england is newcastle and he is calling him a geordie! im i geordie and nobody in newcastle say stuff about the county he says. i told him that he doesn't know anything about football and is calling ronaldo, rooney, berbatov sh*t and like i said im i newcastle fan and i know they are quality players! he has no knowledge about football at all! he thinks our team is the best in the world and he doesnt even know how does formation works out! well anyway i said ronaldo is a good player and he said THAT I DONT know anything about football:S Is there anything for me to ask him online that wont answer? like where does nani come from? is there anything for me to call him? people like him are making me soo mad! i hate people who ignore football like that and call them selves true fans!
