If you read batman comics, or even watch the critically acclaimed and widely respected late 1990s batman cartoon, you will see why the original title was "Detective Comics". Batman is a detective first and a butt-kicker second.
Spiderman was the first superhero with real problems. He is a scientist, a teenager, and a super hero. In the comic world he INVENTED the web shooter device and the fluid that gives him web (even though in the movie it is an organic mutation). He is a problem solver who uses his inventions and his powers in an attempt to solve problems without hurting people, people who want to hurt him.
My DS is a Batman fanatic! He's never seen any Batman TV shows, but instead devours the comic books. Batman is SMART! He has no superpowers, but he invented all this super cool stuff and became an incredible athlete in order to fight crime. He never beats up the bad guys, but rather puts them in jail.
Even cooler - Batman is his real persona; his Bruce Wayne character is fake. He plays Bruce Wayne as a playboy jerk so that no one will suspect that he's Batman.
He has to use his wits alone to figure out whodunit. He's a detective, but one with a cool cape!
We're big Batman fans around here, and IMO, it's absurd to outlaw superheroes!
But I agree with the sentiment of what's good for the goose is good for the gander. If superheroes are gone, then princesses should be, too. I agree 100% with the idea that all licenced characters should be banned.
