For the record, I'm not a trialer or breeder, I'm strictly an end user. Nor am I either a champion of or apologist for trialing, "it is what it is," which from my vantage isn't nearly so bad as you and Ms. Nelson apparently believe, quite the contrary: much more good than bad has come of it.
Are there trial dogs the average Joe couldn't handle? Absolutely. There might even be a successful trial dog out there that couldn't find a cripple in bushel basket. But were there a way to prove it, I'd bet something much better than nice there are far, far and away more problematic dogs, by percentage, outside the circle of trial breedings. Being too dense to see things your way probably makes me a sub-average Joe, but trial bred dogs have handled the load of our commercial hunting needs admirably for the past three decades and been wonderful companions and caretakers for four generations of our family.
If you think I'm wrong, you might be right.
