It is a fallacy of following a man blindly.
Christians have the Bible which details how false prophets are yet many would rather not read, understand and obey the Good Book.
It is also the human psyche to want to be led and charismatic leaders such as Jim Jones, Hitler and other evil men have perpetuated such great evil because of their uncanny hold on their followers. That is why you should always be very wary of following a person blindly.
This mainly applies to cultic-religious figures and movements such as this one and ISIS, political and even celebrities (does Gaza Krew in Kayole ring a bell with their devotion to Vybz Kartel?)
