Hitler was charismatic and very homely and quite insane
FOOTOO is charismatic and very fat and wrinkly and nonsensical
Jim Jones was charismatic and lured people to commit suicide by drinking poison

It is a defect in something that makes some vulnerable while others view it as ridiculous ludicrous cockamamie wackadoodlenoodly. Weird.
