Why do football fans feel like it's necessary to be so snobby about the game?
How about you just let people support whatever club they want? Honestly, I don't see what the big deal is about someone preferring to watch a certain team play and want them to win. I love football, it's a great game, great sport to watch and a great sport to play - but the whole culture built around it is just awful, not just the hooliganism immediately associated with it, I'm talking about the elitism, snobbery and mob mentality involved. You're no better than a United fan by supporting Yeovil.
When I was young, I supported United, not for any glory, not because I liked that they one all the cups - I was absolutely clueless about football. Simply because they were the first team I played as on FIFA '99 because I liked their badge and kit, and there was the lucky coincidence that SAF was being interviewed on tele after I had finished playing. Yet, I was subject to the whole 'glory hunting' debate, I was immediately branded as a Celtic fan too, because I'm Scottish and liked Man United. "The Tims of England", apparently.
Nowadays, I've drifted away from United and find myself preferring Aston Villa and Cardiff City, all 3 of those teams being in completely different countries from my own - I just don't enjoy Scottish football and that's my prerogative. It doesn't make me a bad football fan because I don't support a local team, there are just certain clubs in the world that I enjoy watching and find myself hoping they win.
Live and let live, football fans. It's none of your business why someone supports a certain club, whether that's for glory, enjoyment, locality, or a childhood connection. It simply does not matter.
