That's pathetic. You're also forgetting that it's not just about the child's skill. The child is on an animal that has a brain and can make its own decisions. What if that horse spooks? What if that horse doesn't want to stop? What if that horse is having fun and bucks? It's parents' jobs to protect their children. I am all for kids being around animals, riding, etc, but I think it's a parent's job to make sure they're safe. I'm glad y'all all survived, but saying it's Darwinism is a piss-poor argument. Tell that to the parent who's 5 year old child has severe head trauma because he fell off a horse.
Actually, maybe you're right. Let the stupid parents put their children on horses without helmets. If that kid dies, then that's just one fewer stupid person on this earth!
