I think that you see it more at the lower level local events, and not at more expensive larger events, because it's cheap, easy, and no formal "training" is really required for local gaming. For speed events, you aren't judged by anything. You simply get a time from the clock. And the clock doesn't care if your horse bucked through the whole pattern, for example. You can just show up and drag your horse through the speed events with your spurs and whip.
That said, of course, not everyone at the local level is a "bad rider" nor are their horses complete nutcases. But you get a few people who are and ta-da: Everyone gets a bad name.
As long as you are teaching your daughter and horses the correct way to ride and behave, don't worry about anyone else there. Because you'll see bad examples, especially at the local gaming shows.

It is not enough to know how to ride; one must know how to fall.
