If every hero of the Silver Age had acted like him, I might agree. The fact is that other contemporary characters like The Flash or the Green Lantern weren't behaving like perfect sociopaths like him. They didn't invent complicated tricks to make women believe they were actually crazy. They did not claim to be perfect paradigms of justice and virtue.Silver Age Superman was written for children primarily and falls apart if scrutinized by modern adult sensibilities---as do all funnybook heroes.
Isn't it hypocritical to say you represent "Truth, Justice and The American Way" when in reality you spend a lot of time lying to your loved ones?
