And that brings me to that "villifying riders" statement. IMO, no one is any more or less villified than they are now. You lose the ribbons you won, your name is listed as losing that for a horse's positive piss test. At present, and within this proposed competition, the false positive risk is the same.
If the A Crowd can deal with this at present, then what's the difference between making a Division that primarily varies in that it tests all horses and not at random as USEF-sanctioned shows do?
