I was never a Jehovah's Witness, but I want to chime in.
There's no need for this infighting, it accomplishes nothing and only breaks down the solidarity ex-Witnesses enjoy here, endangering the community this site offers exiting and doubting Witnesses.
On the one hand, I find it hard to believe that this protest will backfire by strengthening the faith of Jehovah's Witnesses. It will most likely have a negligible effect on most, who don't need a protest to feel persecuted: the convention program features several videos which highlight such 'persecution in Russia and Malawi, for instance.
On the other hand, I understand posters' concerns that the protesters themselves may still be allowing their old faith to influence them and that these efforts keep them from healing. This is something the protesters certainly should consider, but a single protest, in and of itself, proves nothing. Everyone is different.
