I'm pretty sure that the "majority" of people aren't here on the forum... no matter how popular it is! Facts are, the majority of people don't show, don't breed and don't educate themselves beyond what they have to.
Obviously, the people here who show, breed and try to choose the best horses they can are NOT going out choosing the horses full of genetic, conformation and disposition flaws!
Coming to this forum and complaining about the public perception of the breed(s) is, quite simply, "preaching to the choir".
I know thats not how you started the post, you were asking for photos... but thats where its going. Yes, changing the publics perception is the key - but how're you going to get out there and remove all the lousy, poorly bred, flaw-ridden fuglys that are out there? And what will you do with them once you've got them off of every street corner?
All we can each do is the best we can do. I put on a booth at the Horse Expo in Pomona, CA this year, pretty much all out of my own pocket - a little $ from one friend, and time spent with several. I got very little support from AMHA or AMHR. An estimated 30,000 people at the event, the biggest in SoCal, and all I got after much begging to both registries was a handfull of pamphlets (each) that was gone well before the event was over.
Proportionately, I spent far more time and money promoting miniatures this year than the registries will! Way to help the breed - and to make the individual breed promoters feel like they are peeing in the wind!
I don't have facts or figures, but I'm guessing that all registries spend more money soliciting advertisements, show entries and registration fees from the people already involved in the breeds than they do promoting their breeds to the public or to owners of other horse breeds. (I know that there was NO representation for Arabians at the horse Expo... no breed booth, nothing in the parade of breeds - nada.) So its not just minis!
Every breed has its stereotype (dogs, cats, horses, even peoples!) I don't think we can stop that - all we can do is get out there and put our best feet forward!
