Monkey see Monkey do, albeit from a Christian perspective.

In some churches they do certain things like being slain in the spirit, where you fall down, after a laying on of hands, speak in tongues, etc... I don't attend churches of many denominations, Charismatic in the early 90s. Anyways I NEVER saw anyone not fall down when brought to the front of the church, and I'm not talking only big churches . I never saw anyone not fall down, its a social aspect

A similar thing in Vigilantes, you can whip a crowd into a frenzy. Mob mentality, Antifa
