Just imagine Brad trying to lead a cult of young, impressionable followers:
Brad: *gives a long, meandering rant about his delusions"
Follower: *Asks for clarification of one point*
Brad: "I AM a teacher, I AM trying to teach you! You have rudely judged me! Therefore, by the powers of Melmac, I sentence you DON'T GO AWAY I NEED YOU!

OKAY FINE YOU'RE ALL GOING TO BE REBORN AS CHICKENS!!!"
Brad's behaviour is a better means to disperse a large group of people than a can of bear spray.
Charles Manson, L. Ron Hubbard, Marshall Applewhite, Shoko Asahara, there's so many people that managed to create completely ridiculous, outright evil cults, yet Brad can't even make his gf of over a decade believe in his nonsense unironically. That must sting.
But at least he didn't run into someone as delusional and crazy as him, otherwise his World Music Orchestra might have turned into a suicide cult, too.
