Well since you posted in the Secular 12 step forum...um...the only requirement for AA membership is a desire to stop drinking.
If someone tries to tell you otherwise, then you know to stay away from that person in the future. I found a lot of dissenting thoughts in AA meetings and those who attend them. "Thanks for your input," seemed to work for me (as I walked away). I think if you find value in attending, why not keep going?
No one can oust you
