I think the problem with the BU when it formed was that it was a mish-mash of aims and objectives to begin with. I admire their adoption of policies at the outset to be inclusive, but they failed to convey what they were about sufficiently in my view.
I believed their raison d'etre was to raise awareness of the Board's inability to take Everton forward, and inability to find someone able to do so, and to try to help facilitate that if at all possible.
I went to some of the meetings, as I'd just returned from living in Asia, and there were some very eloquent and astute Blues, who truly wanted what was best for the club. Unfortunately, at that time we were doing alright on the pitch (although the footy itself wasn't great from memory), and too many people in the wider fanbase thought they were being disruptive. It wasn't about Moyes and the team, it was about ownership, but there were also a few Millie Tants in their ranks who were anti-Moyes and latched their aims onto the BU, causing further alienation within the fanbase. Putty in the hands of the club's spin doctors, able to peddle an anti-BU rhetoric that they maintain to this day.
The club fractured the fanbase during the Kirkby debacle, and those differences remain to this day. The advent of t'interweb has seen people lose the art of debate, and too quickly online discussions degenerate. ToffeeWeb is a really good "bad" example of that during the Kirkby period, and it remains to this day (was never a GOT reader then, sorry).
