It wasn't irrelevant at all, it was central to their argument throughout the campaign from start to finish. How could it not have been when their major point was that the move to Knowsley would take the club outside the core area of it's support and also away from transport hubs and the commercial life of a large city? They were consistent, there was no 'change of tactics'.
That took a back burner to pulling up everything wrong with the transportation, the ground, the deal etc
The "narrow minded" already knew about the move being outside the city but didnt care too much because they had faith in the stadium and what it could offer....they didn't illuminate anything with that because it was already out there.
The things they made the fans aware of was everything else and not what they were initially set up for - solely stopping the club leaving the city
If the move was everything they promised ...they'd just be upset with leaving the city, something every fan knew about. But it turned into a different thing altogether and much bigger than that
