I still think nothing beats noah's ark as unappropriate.... But that's just me..
And I never understood why we can have cowboys and indians, medieval knights, pirates and redcoats, cops and robbers.. the bows and guns and swords and maces and ... aren't to pick flowers... but no soldiers... At least we have machine guns coming next year!
As to the rest, like playmofire said - it's a very "gentle" version of the world.
