But what exactly is the (real) cause, when the MUST guy said himself that they'll go silent again once they are biggest spenders again?
It's easy to hide behind the 50+1 thing when you know full well it won't happen anyway. It's a nice shield to stand behind when you also know full well you'll be quite happy to turn mute if a gangster or sheikh suddenly turns you into the biggest spenders once more.
The coaches thing is not the same. At Anfield it was 99.9% good fans and the odd idiot throwing a bottle. What we have seen in Manchester is probably 5% who know what they are actually there for, and 95% there for a piss-up, a fight with stewards and police, a great excuse for a ruck and to sing anti-scouse songs about poverty whilst supposedly protesting about greed. The overwhelming majority there have no credibility whatsoever, clearly exhibited by their brainless, moronic behaviour.
The money point is entirely relevant (and valid) for United fans to raise, because their argument with the Glazers is that they have taken a fortune out of the club.
If it were 95% dickheads up for a fight, the 30 or 40 police at the initial protest point wouldn't have stopped 1,900 of them, would they? Even when they moved to where they thought our coach was coming in, they were walking calmly.
Football tribalism is great for atmosphere. It makes discussions like this farcical, though.
