Have they been?
In a way, no. The reason they would have been disbanded, is because they attracted such loonies that they couldn't control them, hence the need for expulsions and splinter groups.
As they had been so successful in their publicity campaign, they were attracting more attention from the press and were being asked to me more accountable. This they couldn't handle, because inevitably any close look at them would reveal the holes in their thinking and attitudes to family functioning after break up, and in the personal histories of the men involved. A man like Eddie Gorecki for example, who is or was (I can't remember whether he was chucked out) a lynchpin of the organisation, is so unsavoury, that he simply isn't presentable because his behaviour and attitudes don't stand up to scrutiny.
And in a way, I think the fact that F4J were an umbrella organisation for so many nutters and they were desperately trying to keep them on a leash, means that now there's nowhere for these nutters to go, which may mean more dangerous or lunatic stunts from independent madmen. Batman may have been a twat, but at least he wasn't kidnapping children or putting anyone else's safety at risk.
