While I understand the choice of the name, I too don't think it is the right choice.
Why?
Quite simply because no active dubs will look at it because of what it's called.
For the association to be a real success, you also need inside help and you've just shut the door to all that.
How many of us still "in" will think twice before linking to or liking AAWA's facebook page? With a 'safer' name, we could happily link which in turn will invite active dubs to take a look too. A case in point being this recent post http://www.jehovahs-witness.net/jw/friends/250133/1/A-very-simple-trick-for-helping-JWs-be-nice-to-them-on-YouTube
Would JWFacts have helped so many if it had been called JWlies or antiWT? I really don't think so.
I understand you want to stick to what you've decided as you've already done so much to set everything up, but if that's what everyone is saying is wrong, maybe it's because we do have a valid point. And just maybe it should be taken into account. It will be well worth it later.
If it's any help, I've also known big organizations to change their name, so while yes, it's a hastle, no, it isn't too late to make a change.
Apart from that, it's a wonderful initiative and I really hope it takes off.
