Let’s assume you’re right handed. Isn’t it easier to “hit” with you’re right hand and forearm than it is to “drag” with the back of your left palm?
For the millions of golfers out there who have been brainwashed by the doctrine, you DO NOT hit with the left hand, arm, etc. You hit with the right side! The left is for stability only!
For the golf swing scientists out there, argue amongst yourselves please: then go out and chop a tree by hitting with your left. I’ll come and visit you in the hospital!
