If the “he” you are referring to is Cruise, he is not the head a scientology. That distinction goes to a man named David Miscavige.
To your point about a weird culture I tend to agree.
Anyone who hasn’t seen Leah Remini’s documentary “Leah Remini: Scientology and the Aftermath” needs to....scientology is worse than I thought.
Cult not culture
I saw it. Eye opener. Miscaviage, who is even shorter than Cruise, recruited him and he’s essentially his second in “command”.
