Funnily enough, I don't worry about this stuff with (younger) DD - I'm pretty confident that, like me, she'd just call BS and move on with the story. DS though.... I feel like he needs to be explicitly trained to be more critical, and be aware of the need to actively reject rather than absorb the stereotypes, while still enjoying the story.

His father was brought up neanderthal; perhaps I am a little overcompensating!
