I watched not even five minutes of Astro boy and when it came out I heard there was a lot of political propaganda and undertones. I saw it one day on tv and this was the first thing I here "Hooray we saved the day and defeated the evil cooperation! Now we can pass the healthcare plan".I’m like what! They did not just say what I think they Did. That was a huge reference that could not be ignored . What would little kids know about healthcare?

The character HIM is the only cross dresser in the show. And he's a villain. Not just a villain but the devil. Message: anything queer or genderqueer is evil.
Princess Morbucks is in every way a spoiled rich girl. She's the only wealthy character in the show. (At least Batman is a good guy!) Message: Rich people are and will always be evil.
Gangreen Gang are the only humans that are green. They're also homeless. All other human villains are Caucasian. CN doesn't allow many ethnic villains because it perpetuates stereotypes. Making them green was a loop hole. Message: Colored people are dangerous.
The episode "Equal Fights" is a total mockery of the equal rights movement. Message: Equality has been achieved there's nothing else to fight for.
Femme Fatale is the only character that identifies herself as a feminist. And she's a villain and a man hater. Message: Feminism is the enemy to women.
In the episode "Custody Battle" HIM resurrects the evil Rowdyruff Boys (originally created by Mojo Jojo.) Mojo and HIM argue over who the father is. In the end the two settle their differences and end up happily together. Oh an HIM made the boys impervious to girl kisses. Message: Do I need explain how anti gay parenting this is?
The episode "See Me, Feel Me, Gnomey" features the girls giving up their power to a red clad gnome for peace. Peace is achieved after the gnome gives us some satanic chants and everyone in Townsville is wearing red robes. The Professor informs us that things are worse than ever and they gave up freedom. Enlightened the girls beat up the gnome for tricking them. Message: Communism was made by the devil! Hippies are commies. Russians are commies. Let's beat up commies!
See Me, Feel Me, Gnomey was banned but it's unclear if it's because of the capitalist vs communist message or strobing backgrounds. I must admit that over all, I do love the series, and all the villains.
Femme Fatale does not symbolize modern feminism but feminism as a whole. At the end she is compared to Susan B. Anthony. Femme Fatale went to jail for robbing banks but Susan B. Anthony went to jail when she tried to vote.
"Sure, right after I vote no on proposition 54"
