The AOA needs to take the high road and accept him.
Yes, I agree it would have been much better if he were already a member and it's poor form on his part that he's joining only now when it suits him. Some people just have to learn the hard way.
But the AOA as a whole is above all of this. We should show some compassion to one of our own, even if we don't agree with what he did. Any one of us could be in his situation with the Company on the war path these days. Look at the fleet office. Protecting their boys from the pressures above? I don't think so... they're looking for the next person to be thrown under the bus... if that isn't something to rally and solidify the AOA's membership, I don't know what is.
