Shaman, it doesn't really matter a tuppeny damn what the politics are, the fact is, BALPA disaffected a proportion of it's membership, to the point where the left, with their money.
However you wish to huff and puff about it, it was a pi55-poor way for BALPA management ot bite the hand that fed them.
No dog in this fight, not even in Aviation......so, if an outsider can see it, I suggest you take a few paces back, remove the rose-tinted specs and view the scene objectively.
