A more holistic approach, one that seeks to free individuals and families from all manner of cultish organisation, would be much more difficult to undermine and more likely to win wider acceptance from the population at large.
It would be THE most effective approach. Imagine if an ex mormon was able to put together examples from their literature of the same mind control tactics used by the JWs. Another mormon would run scared from such 'apostate literature' and vice versa.
Steve Hassan's website does not provide this. There is a massive gap for a website drawing parallels between cult practices from their own literature.
