> Most Americans wouldn't consider Charlie Brown the "hero" of his strip, they would consider him a loser who gets what he deserves, and that's the joke.
I don't think you speak for most Americans. That's the cruelest interpretation I've ever heard of Charlie Brown.
Real life is cruel to the Charlie Browns of the world.
And from what I've seen of the cruelty and lack of empathy in American culture, I stand by my assessment.
