I think this boy did what most boys would do - but like you I would probably have turned and run as fast as I could.
The video ends with the news anchor saying government officials say to contact animal control if you see a fox in your area....
Only problem with that is in the “heat” of an attack....well...using whatever weapon you have available seems a pretty normal approach to me also.
I guess my surprise was that so many thought the FOX was justified in attacking the teen.....sorry but good grief!
