I agree with this.
In all honestly, they probably won't give your horse a look, that is just how those kind of judges are. They want slow.low. and that is all they are looking for, which would be pretty hard to teach a Gaited Horse.
I know how your feeling, I have a gaited horse (TWH) and I want to show him at local shows at well, knowing this I am doing it to get experience and show off what he can do, no matter what people think.
I have taught him long and low for the head, and a relaxed body; which I feel is very important no matter the breed.
If your going into English, or just need some suggestions, I would highly recommend looking up "Naturally Gaited" on Facebook or she has a website.
She competes with her horse in all different types of things: Western, English, Jumping, etc and she is very open to helping people. She has helped me a lot.
Good luck, if you need some more suggestions feel free to message me.
if you want to show or compete, you can either do so against yourself for your own satisfaction and judge yourself. Or you can walk the party line and do what everyone else does. Simply not really any way around it. Western people wanna see stock horses, english people wanna see TB and warmbloods, Others need not apply. Just the way it is.
I say get the horse you want , do what you want and enjoy it,
