Did I say your horse was "crappy?" No, I did not. I don't even know your horse, so how can I possibly know if it is high or low quality, or if it deserves to win or not? But I am saying that, when others place higher on a consistent basis (which is what you are implying), then that is almost certainly do to them being better horses rather than the individual judge's "preference." Look at the horses posted above who have won--does it look to you like judges are bashing them because of their coloration?
I read in Paint Horse Journal a few years ago that in halter, and halter alone, there were a few ex-AQHA judges that were knocking high-white horses because the white spots were obscuring their conformation. There was a mild controversy, the problem was settled, and there was no more talk of biased judges after that time.
I own two Paint horses. One of them is extremely flashy and beautifully marked. The other is a minimal white overo who's only Paint characteristic comes from a broad apron face. The former is the prettier horse, but the latter is a much higher quality animal. Color has nothing to do with it.
