To be honest, I think the greater benefit will be about building support amongst ourselves - ie the fans. I think there are plenty of people who oppose Glazer but don't want to stand out as being one of a minority kicking up a fuss.
The green and gold gives people an opporunity to say to other fans "I'm taking this seriously", and I'm pretty sure, as word spread, the numbers earing it would increase over the weeks. Once there is a substantial proportion of fans in the colours, nobody can be in any dobut about how many people are behind the movement, building everybody's confidence to make themselves heard.
The kind of thing I'm talking about is, just say somebody here has a seat in NT3, and they can here Glazer chants going up in the Stretty. Normally, the reason the quiet areas don't join in songs is because there aren't enough "instigators" who will pick up a song coming over from the Stretty. But it if that person can see a good helping of green adn gold shirts around him, then he at least know that if he gets it started its likely people will join in, rather than leave him standing there like a muppet singing by himself.
