That reads like he didn't want to encourage the fans as a group to boycott? Can't see much wrong with that, it would be like somebody from the trust quitting because they didn't agree with the Trust encouraging fans to go inside sixfields (fair enough both ways)
He resigned because the group wanted to remain impartial. Allow all to make there own minds up. Some go to Sixfields, some don't and everyone gets on well enough. The guy has a chip on his shoulder
