It's multifaceted. The scab thing is like the blood on Lady Macbeth's hands: "all the perfumes of Arabia" can't rid them of it. "What's done cannot be undone". It's associated with the pit closures; the deindustrialisation of Britain and the state of the country now. Class betrayal - selling out their own. Brian Clough thought the same, which must sting some. When they sing "sign on" it betrays everything a club like them should stand for, and many generations of none Scab Notts miners. It's the equivalent of Liverpool's Munich chants and Man Utd's Hillsborough chants in my mind. Irredeemable. The claim that it was years ago is totally irrelevant: if you grew up in a mining community the scars are very much still there (ironically most of them do). If you are working class it's still there. If you're from a mining family it has been infecting the generations of that family and their life chances. I'm all of that, so in my mind the "scab" chant is the least they deserve. My grandfather was involved in WW2 and was seriously injured in a mining accident at Brookhouse colliery; he wanted Thatcher and the scabs to burn in hell.
They were always arrogant bastards. Every time they've lost to us they've cried like babies. Anyone remember "2-0 to the famous team" when they lost in the play offs? Or their attitude when we beat them in the cup when we were on our uppers? Totally nauseating. They're a club followed largely by atavistic simpletons with no understanding of the past or the present. They now have a seriously dodgy owner who they worship. "Owt for a pound note" as they say.
The carry on after the play off game was a total joke. Not only was it a pitch invasion - the vast MAJORITY of the pitch invaders charged the away end. Coins, smoke bombs etc. It wasn't a celebration, it was an attempt at a mass violent altercation. I had kids with me and they were genuinely scared. If it wasn't for the restraint of Blades supporters and a close run intervention from the coppers, you'd have been looking at one of the worst clashes in a ground I can ever remember. It was totally classless. Conversely, Sharp was all class after the coward attacked him from behind. Rather than total condemnation and credit for our restraint, the fucking morons tried to pin a viiolent attack on a kid in a moon boot and another with a serious hamstring injury, -players who were more than justified in being on the pitch to clap off their fans after the last game of our season (as tradition dictates). Again, what did Cloughie do to their morons on the pitch back in the day? They were a fucking disgrace and didn't hold their hands up. They deflected and did everything to pass the book. Even the club employees were a disgrace.
