I did say that breed people are the minority, not that they're a tiny minority. I know one (1) person who shows AQHA and she is an AQHA breeder.
I suspect this might be a national difference. I’m in the US, and we have a ton of solely AQHA show folks.
I like Arabs too (not to hijack too much). I own a QH, a saddlebred and an Arab
My chosen discipline is dressage, but I enjoy the “non traditional” breeds. My saddlebred is a super talented dressage horse but very typey from a saddlebred perspective.
Anyway - I can see your perspective - different equine areas are very...different.
