Visible protest gets the media on the bandwagon, and it hopefully snowballs from there.
Even a simple thing like fans not leaving the concourse til 5 mins in next week so Sky show a completely empty bowl would be massively ignored(not that ot would make Ashley quit like but would show fans are fighting together). Sadly for every active fan wanting to at least show some form of protest theres 10 happy to sit on their hands and continue to 'support the team' as anything involving effort isnt for them.
Team would probably play better with the walk out tbh without the 40,000 idiots screaming at there every move. They seem to manage well enough in front of the few thousand actually supporting them away from home.
sorry Alan.
