Techincally, when you say "Karate" only systems from Japan/Okinawa can truely be considered. True Kara-te has nothing to do with TKD, BJJ, Muay Thai, Kung Fu, ect. In my opinion even "American Karate" systems are not Karate at all, and it kind of pains me when I see signs at TKD schools or "freestyle" schools calling themselves Karate... but that's just me. The term Karate is being used to broadly nowadays.
