It is really sad to see what is happening here. As an outsider, I think the idea and the cause of AWAA is nobel and effective to bring down the WTBS, and also to help the ex-JWs, JWs as well as the bring awareness to the public about the JW cult. On order to see something done successfully all need to be united, and not divided. And the CORE mission/policy/purpose of the movement must be observe carefully and devotedly.
The interest of your target group that you want to help (if that is your objective) should be the first priority. If AWAA wants to united "apostates" or even faders/mentally-out-physically-in JWs to form a strong force to fight the cult, then it should take the interest, welfare and opinion of the members seriously. One can always add a friend into a group without the person's consent or knowledge and this is so true. I myself had been added by friends into some political groups, even a secret group, without my consent and knowledge. Thus, in the case of AWAA, many will actually have to innocently suffer the consequences of being added into the group.
Probably if AWAA really needs to have a group in FB, they can name their FB group with a more subtle name, not the obvious ANTI-WT-AA. Just my 2 cents.
