Ouch, as a Paint person that hurts!
Sorry. If it makes you feel any better, I've the same opinion of all Warmblood registeries.
BUT... It is just my opinion. And I'm not saying that Paints are bad horses, I just don't think that they are really a true breed. When I see an APHA registered horse that's got QH and TB as well as Paint - Well, that's just a crossbred horse, papers or not. I don't really get how that could be considered a purebred.
I'm not a Paint person myself. I've never liked them as a breed, don't ever see myself actually liking them. I've trained several nice minded Paints that turned into really nice horses. I've trained some pretty stupid ones. Trained some really nice Quarter Horses and Arabians, met some pretty stupid ones too. IMO - a good horse has a good head on it's shoulders, regardless of pedigree or colour or breed even.
Breeding Arabians I hear it all the time about those "crazy psycho horses" that I don't really care if people don't like "my" breed or not, so I'm not trying to offend you or anyone else who breed Paints, because what works for me might not work for you, and vice versa. And that's okay.
I just don't really understand APHA and breeding purebred Paints when there's three different breeds half the time on the horses papers.
