Some proper rubbish getting spouted here. People having a go at fans who choose not to go to games is just cringeworthy. Everyone is entitled to make whatever choices they want in that regard, and i've thought many times about packing it in myself.
I've had a season ticket for 20 years, travel up from London for every home game and go to 7 or 8 aways a year. I don't do it because i'm a superfan and think my support is crucial to the team, or because I love every second I spend at the match. I do it because it's my hobby, and i'd be at a bit of a loss of what to do if I stopped. We go the game, it's what we do.
