I don't have the time to refute everything you just said, but that is completely false. It is a fundamental misunderstanding of what force and acceleration is. I learnt in middle school physics that any change of velocity (speed) is an acceleration. That's one of the few things taught in middle school physics which is absolutely accurate. Any acceleration of an object is caused by a force. I also specifically explained that the force that hurt you isn't the force that causes the deceleration in flight, it's the force that causes the arrow to decelerate rapidly upon hitting something (technically, the reaction force of Newton's 3rd). I can't explain this any more clearly than that to you.Deceleration decreases force, it doesn't create force. Deceleration only means the object is slowing down, that in itself wouldn't hurt you. In fact it would help the guy being hit, as that means the arrow wouldn't be as powerful when it hits him.
You don't understand the very basic physics, please try and learn it, and don't press points about the physics until you do.
Also please stop trying to lecture me on physics, you're wasting your time and embarrassing yourself further. I have 10 years education in physics, including two masters and a PhD in it, and am writing this post from my office in a physics research institute. You're one of the posters I respect the most on here but you seem to be deliberately losing credibility as fast as you can.
