Personally, I have a low opinion of the intelligence of people who go out in wilderness areas inhabited by large predators unarmed. His inane dialogue, “Dude!” had me rooting for the lion very soon.
If I were in his position, I’d have gotten fed up with that lion’s chutzpah early on and picked up a nice large rock or a stout stick and gone on the offensive. I suspect that lion would have run as soon as she saw a human bend over and pick up a rock. She certainly would have run if the human advanced on her with visible belligerent intent.
The nudists and vegetarians at the Mountain Lion Foundation, naturally, have rushed to defend that insolent lion’s behavior, and, of course, they think the millennial did exactly the right things. (groan!)
