The clear signs of a cult. Notice the excessive overcompensation, big flags, big signs, overly aggressive, etc.
"The fanatic is perpetually incomplete and insecure. He cannot generate self-assurance out of his individual resources - out of his rejected self - but finds it only by clinging passionately to whatever support he happens to embrace. This passionate attachment is the essence of his blind devotion and religiosity, and he sees in it the source of all virtue and strength - He easily sees himself as the supporter and defender of the holy cause to which he clings. And he is ready to sacrifice his life." - Eric Hoffer
