Well, for those who think it is, look at at this way.
Simpson has been found guilty in a British court of a crime.
The Three Dunces have not been charged with anything, let alone found guilty. In fact it's not clear that it would be possible to charge them with anything outside of the kangaroo court of fans forums, with the charge effectively "being an embarrassment to the club".
This means that the club has an easy, but more importantly - legal, way to break Simpson's contract. It is not clear that the club can do this to these other fellas, who can point at higher profile players having done the same, without facing a lawsuit. Plenty of people on here have said they want to see the back of them, but I'd hope that they'd all want the club to act within the law of the land.
As you say, *sigh*
