Jeff - The problem is most, many people do not know what "appropriate use" is. Define it for me please.
For myself, appropriate use is if the cows life is endangered, such as stuck somewhere or down after a hard pull. For myself, if a cow refuses to go down an alley or into a chute, I have done something to create an issue, so I fix it. I do not fix the cow. As limmiman said, you can change their attitude by changing their minds.
Low stress handling comes from the humans and is transferred to the cows. Beating on a cow with a stick is just as bad as using a hot shot. I have seen people use a stick with a plastic sack tied to the end and that works fantastic!
To say if someone attends a Grandin class they are automatically an expert on working cattle is asinine. I have attending computer programming classes, but I still have no idea how to write a computer program. I have also attended organic, all natural food source seminars, but I certainly didn't "buy into it", and therefore am not "practicing" what they taught.
Again, my fear is that with the public having more and more influence on how we produce food, we MUST get smarter, better, more humane at what we do. Unless of course, you have no cares about the future generations and their ability to produce food.
