But they don't exist "as created". They were adapted, too. And after a long break, so more abruptly than the gradual (but absolutely evolving over time) ones that did so more slowly. They don't hold the same opinions and characterizations they did in the 1940s. They don't, as a whole, act like people of that time (or even necessarily how they acted in their 1940s comics). They are much more like historical fiction where character often have more modern attitudes despite a historical setting. Not that Earth Two originally had a historical setting. So at least them changing made sense in light of people changing as society changes all the time, and there being a timeskip. Or maybe it's more like alternate history fiction?
