Better not let them watch the news or learn about history either. Those things are "harmful." In fact, maybe you should place blinders over their eyes and lock them up inside. It's the only way to be safe.
Also I don't like all this complaining about the ride being "scary" for little kids. What are they going to do next, tear down the Haunted Mansion? Give me a break. Being scared once in a while is not a bad thing. If a parent didn't think the ride was "scary" that's their fault for not learning how to read.
I'm fairly certain they were joking. Let's not go into the deep end here over this ride....
