YOu seem to be here as a troll and/or a cult apologist.
Rebecca Moore is a cult apologist who engages in the worst sort of apologies about Jim Jones. She worked to include his name on a memorial at a cemetery where there is a mass grave of Jones' victims. Jones is not buried there, but Moore wanted his name engraved on the memorial stone at the mass grave anyway.
To be extremely charitable--Moore's theories are less than credible.
And there are other apologists that have been paid by cults like Eileen Barker, Gordon Melton and Dick Anthony.
The label "new religious movements" is barely relevant as many groups called "cults" (e.g. NXIVM) are not even religious.
Einstein's theory of relativity is no less relevant today than it was decades ago and Galileo's basic observations and theories remain relevant after centuries. The writings of Robert Jay Lifton, Edgar Schein, Robert Cialdini and researchers like Singer, Conway and Siegelman, Zimbardo and Milgram remain directly relevant to the cult phenomenon today.
Moore is little more than a minor academic hack without any stature other than her personal family ties to Jonestown, which makes her less than objective.
You seem to be here to undermine this thread and attack people that post here personally. If I receive just one more complaint about you--you will be banned from this message board.
No one is really benefiting from your posts other than the cults.
