I was pretty sure he was not proposing that someone should have to be hurt.

However, I wanted to make a point, first for beginners who are reading, and second for instructors. Those of us with experience need to be sure we help new people develop safe habits while they are learning.
I see way too many people being slack when it comes to prop safety. At the field today one of the combat guys was sitting on the ground starting his plane by holding it in one hand and applying the starter with the other. Unfortunately, the prop arc was pointing right at his body. I thought about saying something, but I've been sensitized that some people don't want such "help".
