When Southern was wound up and AIPA was approached for support they pissed on us from a great height
Hang on, AFAP were your respondents to the award at the time. I also recall AIPA having been rebuffed on some occasions in there also. I don't deny AIPA's rules at the time prohibiting membership by regionals- rules that took too long to amend despite a number of mainline crew asking for them to be amended- but the situation is far more nuanced than what you indicate.
Of course, if you know the situation then you know that's the case. If you don't or if you have ulterior motives then you articulate the point that AIPA 'pissed on ' Southern at that time.
