Teaching our little girls to say trashy things about boys is not the road to equality.
Here's why:
2. No human is a waste of time. Saying this to your brother is "cute" but also cruel.
Teaching one to disrespect the other does the opposite of this on all points.
"It's not like they directly attack anyone, it's more social. They want you to feel bad. They give you mean looks. They find ways to hurt certain people..."
When we encourage little girls to say, "Boys are a waste of time!" in any variant, we are teaching them to be mean little girls who grow up to be mean teen bullies.
These parents didn't teach their daughter this because they want her to focus on her studies and personal development.
They want her to maintain her "purity" and it's shame-filled dangerous trash.
But it doesn't look like Biff in Back to the Future and that's what he means.
