Is Karate an affective Martial Art?

Actually karate is better for the street then the ring. If some one grabs me n the street He loses an eye or gets his arm broken. If he leads with a jab a side kick to the knee. If he shoots on me a hammer fist on the back of the head (which is illegal in MMA) ear drums get popped their are many things that you can do with karate if well trained.

 

People talk about the kicks being not effective first of all you donot start a technique with a kick you start with a hand technique then follow up with a kick
