I've always felt it's your beliefs, values and traditions. Mine are working class and I feel this is what defines me. At least I hope it does as I feel quite strongly about my job not defining me.
I'm from Newhaven, it's definitely working class IMHO. That's one Sussex town to counter your "This does not apply to anywhere in Sussex" assertion. There are plenty of others. Also Brighton has huge swathes of areas out to the west and east which i consider working class.
We are talking about Brighton supporter base which spreads far beyond Brighton. I'd argue that Brighton has huge areas of working class. And Sussex certainly does.
Fair point. My angle is the working class. Bad choice of word from me. My point is that the current high prices possibly now exclude a section of society traditionally associated with the game we love and youngsters/the next generation.
