Time for humor!
ANYone could be susceptible to idealistic cult recruitment, or the idea of a charming manipulator, when caught at a vulnerable time. We ALL experience times of vulnerability and life change, such as leaving for college, divorce, loss of job, death of a loved one. Intelligence is not protective against cults or extreme idealism.
At such times, idealistic religion or cult (seems to) offer self-definition and life purpose. One, of many, key distinction for a cult is the emphasis on recruitment and fundraising, regardless of the group’s deemed façade. The new ideals and life mission seem to help the person initially, but then generate a changed persona with the use of scripted language.
Even Wile E. Coyote could be susceptible! :
(note: this is not a criticism of Christianity, per se, but a joke about adopting all-consuming ideology for life purpose)
