Not a bad idea, I like the idea of wearing away colours more as above poster said, a bit like manure do with the green and gold scarves. People need to know what the protest is against though, is it Bulletproof Tony and Waggot, or Venkies as well.
I don't understand supporters who just walk away completely, not really supporters in my eyes ( nothing stopping you going away games only). Don't forget it's Our Club and Town, I certainly will not be pushed out of my home town club by clueless owners or employees only there for a wage.
A protest with a common goal with All fans pulling in the same direction will ask more questions of those at the top. In the unlikely event we do get back to the premiership any time soon I hope those that have walked away for good don't come crawling back. Support for your club should be through good times and bad.
