if id come all the way from Bristol to Brighton on a Tuesday to watch my team get beaten I'd be pissed off too.
And there are, demonstrably, a lot of JCLs at the AMEX which means little atmosphere and noise. The generation after this one will be embedded Brighton fans. A hell of a lot of our support were Chelsea or Man Utd. Fans until a few years ago don't forget. Just look at the NSC join dates to see how there has been a huge influx of new supporters. And welcome they are too.
I joined Aug 2011 but went to my first match in 1977, did the gillingham thing and was a withdean season ticket holder. Join dates mean nothing.
