Re: Does anybody still believe Kung Fu is effective in a real fight?
Kung Fu in actual warfare probably looked different than it does now.
I doubt the artistic qualities of kung fu would have emerged during times of war/conflict.
So in short - yes there are useful applications that would work against untrained people.
But like Sumo wrestling, the art form is too fargone from its actual practical form to actually compete against other martial arts that are used in competition today.
To remain functional, the art has to be used in real competition and tournaments. There may be kung fu tournaments around, but probably 90% or more practitioners use it strictly for demos, exhibitions, general fitness & wellness with no interest in competing.
That kid who was talking smack probably just watches too much martial arts movies.
If there's one thing that early UFC events taught the world, it's that beautiful martial arts were no match against styles that were uglier and less spectacular (wrestling, boxing, jiu-jitsu).
