This commercial from Always, depicts how teen/adult women, and young males, have internalized femmephobia and display it when being asked to run like a girl. versus how younger girls react to that, and then they confront what that statement really means. With a focus on how that impacts young girls confidence. https://www.youtube.com/watch?v=qtDMyGjYlMg
On Saturday Night Live and in countless comedy sketches, a man dressed in feminine clothing is automatically the joke — the audience laughs the moment he walks out in a dress or heels, before he's even said anything. I started noticing how often my kids laughed at this without knowing why.
In almost every superhero movie aimed at kids, female characters who are 'too girly' are either comic relief or need to be saved. Meanwhile, female characters who are taken seriously are always coded as masculine — short hair, dark clothes, 'tough' personalities. My daughter noticed this herself and said 'girls have to act like boys to be important.'
