I’m not surprised of that. I knew some people in Indonesian village also hold similar belief.
I could be wrong but I think csmusaret was making fun of the author’s assertion that “Crazy Horse was adamant” about not being photographed. The only evidence I’m aware of that he didn’t want his picture taken is that there are no pictures of him. By that logic it could be said that I have never driven a car because there are no pictures of me driving a car.
