Firstly I have seen no 'concentrated effort' by anyone to educate the masses. I have seen individuals express in public their doubts about the McCanns and individuals with the same doubts agreeing. That their opinions doesn't match yours is unfortunate but hey, that's democracy for you.
Secondly claiming that hundreds of people have been added to Facebook pages without their knowledge is a serious allegation and one I hope you can back up with a cite.
Thirdly no one joins a sceptic group unless they have had serious doubts about the perceived narrative already, why would they ?
Firstly, well you would say that wouldn't you?
Secondly, my cite will be forthcoming once I've had your cite (previously requested by me) for the hundreds of thousands of people that liked the OFM FB page almost overnight. Inciddentally I didn't claim 100s had been added without their knowledge, re-read my post.
Thirdly, are you telling me that no one has ever joined a sceptic group (wittingly or unwittingly) out of curiosity or because a friend was already in the group and added them without their asking?
