So what is it?

This is something that bothers me. Quite a few times in life I've been told that my punching is not ''karate punching'' that it's just ''boxing''.

That I don't do this twist here or that I don't punch from the hip there or that I punch from a guard and so on...

When I try to explain that it is a Karate punch because of the body mechanics behind it, the way I use my legs, my core and so on I get looked at funny by most and then I realize I'm wasting my time with those people.

But the general question here is. What makes a punch a Karate punch. What is the Karate technique for you.
