I guess I don't see where anyone on this thread has insulted the quality of your horses . . . So I don't see where anyone needed to be proven wrong. The best thing to do is worry about what YOU think of your horses. You paid for or bred them, you feed them, you clean their stalls, you condition them, you show them, etc etc. So what other people think doesn't matter. Unless of course, you openly ask for their opinion, in which case, you are sure to get it, and you shouldn't be surprised by what you hear, as everyone has their own opinion . . . and if you asked for it, well, you asked for it, so no reason to get upset when people give you what you asked for.
Congrats on your successful show.
