Actually, my source is in the middle of the QH AND Paint world, which is not btw, in Northern Utah, Michigan or Indiana.
They are very involved in many aspects and as I've stated already, are friends or acquaintances of most anyone who's anybody in that sector of the equine world. That includes the last decade+ of world champion riders and trainers...many of whom are clients of my source. That isn't an exaggeration, it's a fact and I've been in many of the barns of those champion riders and trainers.
Of course I am aware that QH now allows excess white - I am also aware of the embryo transfer rules, HYPP, Herda debates rules, ad nauseum - I keep up with AQHA but since the question was APHA that man should have known that - I didn't think I needed to clarify in my answer that excess white QUARTER HORSES are eligible for registration in the AQHA!
He's trying to argue the most ridiculous point - they are in fact a separate breed - that simple - it's not different than arguing are QH's & TB's the same breed because the QH originated from a lot of TB stock in the foundation stages.
And as for showing - showing at the APHA world is big *poo* - ask him how many horses where actually in the class - although on second thought there were probably a lot in the non -colored class - since yes they have a handful of classes at PAINT shows and most breeders end up with a gut load of non-colored stuff - why can't they show AQHA if they are just a QH?
As for value - sit through the sale at APHA world sale once. If he thinks your source isn't as well informed as he thinks, fine - but if I realized we needed to argue semantics and make sure our posts included every single nuance of the registration and showing processes I'd have given a more clear answer.
Everything else aside, the question is valid...if Paints were in fact 'Quarter Horses', then the non-colored Paints would be allowed to show AQHA. However, they are not, because the AQHA does not recognized them as Quarter Horses.
They are different breeds but they share far too many of the same bloodlines and characteristics to be completely unrelated.
Well, thank you for finally stating that they are indeed a different breed. I do believe that's what I said orginally that you argued against.
That they resemble each other within the same discipline at the upper level was never relevant to what I said, nor was it something I was arguing. That simply goes without saying.
The fact remains, I can usually tell them apart because I see differences in them structural (in general), and have often found their temperaments to be different (in general).
