They’re both prolific authors and arrogant twits; but do they have anything else in common?

Both authors are bat-shit insane, so I’d imagine there would be a connection.

I just can’t fight this feeling anymore

Funny thing is, despite Professor Lockhart’s ego, I see Chamber of Secrets and don’t think he’s that terrible a person. So many people in the series are vile, overly strict, discriminatory, etc. and we are led to hate him despite his relative agreeableness just because he thinks highly of himself?

L Ron Hubbard, on the other hand, used his power to amass a personal army that acted as a human beehive and even had his followers successfully infiltrate the White House in a revenge plot called Operation Snow White. Despite me positing here that cults are not necessarily “bad”, being so absolutist isn’t great. They both might indulge themselves but Lockhart expressed no intent to sabotage Hogwarts.
