this might seem a little deep, but i think the team you support tends to dictate your personality.
obviously im a blue, but one of my mates is a part time united fan and always seems to not get that interested in anything not just football.
Another mate is also rag (im from Cheshire along with my mates and thats quite close to Manchester and Merseyside so theres only ever City,United,Lpool and Everton fans) but hes actually quite loyal and goes regularly, but he seems to be insecure when losing and will often quit if things dont start going his way.
My closest mate is an Everton fan. cut a long story short hes bitter about absolutely everything, and he often likes to say he hated City before they got good, and of course being an evertonian he still maintains that 1) man for man Everton have a better team and 2) Lionel Messi wouldnt make Everton a better team..........
whereas I, i can take defeat, however when the next oppurtunity comes around i make bloody well sure ive won or died trying. and if im honest had i supported a different team i dont think id have that attitude towards life or rugby.
in relation to your question i have a soft spot for Sheffield Wednesday
