the fact that when i ask "sifu, why don't we kick head level.." and he replays "your groing is unprotected..."
is why i might think is fake...that is a reason but its a dumb one

if you have fast and powerful kicks, there is no one someone can kick you in the groing..

1/100 times maybe...but hardly..
what about TKD artists..in sparring, when they kick high, do they get hit all the time in the groing?

Do you see where i'm going with this?
