I don't have a problem with rodeo either. Just like in any other sport, horse related or not, there are some that are unsavory places, but that doesn't mean you should judge the whole group by the few bad apples.
The only thing that makes me cringe when I watch it, is the calf roping, when the horse gets a little too excited and starts dragging the calf across the arena by his neck or legs. I know that in real ranch life, roping and branding, etc, are necessary but it upsets me to see it done in an arena. But I am the first to admit that is just me being a softie, and that the animal more than likely isn't hurt by it, though it seems they would be.
