Well said! This holier than thou attitude some people out here are expressing about desensitizing a horse completely simply shows some people don't know horses very well. I only hope someone finds in their heart to be kind enough to help them get back up when someday they find that their horse is not as immune to fear as they seem to believe it is. Maybe they are simply currently handling a dead blood and don't realize top horses are more sensitive and prone to spooks and shies when presented with certain situations.
I also agree that deliberate attempts to scare horses happen all the time and you can never prepare for those, either. If someone comes roaring down the road with a car aimed at my horse, I would like to count on his self preservation instincts to get us both out of harms way!
