Out of fairness I read your post through and, although it's well constructed, it's badly informed and full of speculative fantasy
I won't bother going through it blow by blow as it's mainly typical 'Sky Sports opinions' from watching too much TV.
But I've highlighted the most ridiculous bit ....
"..... the thing that struck me the most when hearing Mackems talk was how they felt it was Sunderland's right to be in the Prem, their right to be splashing the cash on big name signings, their right to be above the Geordies."
... if you can bump posts , from Sunderland supporters on here, claiming we have the right to be in the Prem, splashing big money or above Newcastle then I'll happily admit I'm wrong. In reality I think you've invented it to back up what you think is an argument.
As for 'a full house, fired up and hostile, roaring the team to a 3-0 win ...
.... where did the Leeds supporters go so badly wrong against Preston and Fulham
And why did the 3000 'loyal Leeds supporters' lose faith so quickly and not return for the 2nd match ......
