Having thought about this some more, I’m afraid to say I think it’s the wrong strategy being pursued in the wrong way.
Calling for a boycott sounds great to the fans already boycotting, but to the fans who aren’t, there’s nothing in the letter to make them consider doing so.
1) It’s directed to the wrong audience - it’s a letter to the owners, not the attending fans.
2) “The Coalition” calling for a boycott is a long way from Red Robbo calling out the lads at Longbridge. They are by no means widely accepted as the voice of the majority.
3) There is no argument, persuasion or rationale in the letter as to why a boycott will change anything.
4) It’s too long, repetitious and reads like it was written by a committee (no doubt it was). It’s not exactly the Gettysburg Address or the “Liberté, Égalité, Fraternité” of the French Revolution.
When the ground isn’t empty against Watford, all that will have been achieved is a further loss in credibility.
