"Recoil in distaste"

I felt much the same when being taught how to prop start an airplane engine after being told never to put any of my body parts in the propeller arc.

It's potentially hazardous if not done absolutely correctly, but sometimes it has to be done. Best learn how. And don't screw up.

This is a great discussion and I appreciate you pointing out how I presume to speak for others. Of course, that's not my intent.
