I don't understand the concern about the possibility of BK theming involving people killing dragons. If it is a coaster ride, how much plot can you work into scenary when you're going 30 to 50 mph or being inverted? At the most, I can see them having dragons "attacking" the ride cars as they go by.
And, let's face it, the prince killed a dragon in Sleeping Beauty - who was really a WOMAN. Nobody thought the worst when that sword went *THUNK* into the dragon's heart...
And, what do you think the Seven Dwarves were going to do to the crippled old woman (okay, okay, really a healthy evil queen, but still a WOMAN) if they caught her with those sticks and axes? Sing off key to her?
Besides, dragons are MYTHICAL creatures. They don't exist. Never have. Never will.
