"To my mind, this embracing of what were unambiguously children's characters at their mid-20th century inception seems to indicate a retreat from the admittedly overwhelming complexities of modern existence," he wrote to Ó Méalóid.
It's not untrue ... but it is incomplete to the point of misleading. Sure, mainstream comics today have a lot of isms that should be wasms, and sometimes they churn morality to gray goo. Comics haven't always been for children alone, though, and many of them are written for adults today. Furthermore, diversity is exploding if you look at indie comics instead of just the overlord corporations. We have women, queerfolk, people of color, all different religions, etc. all making superheroes and supervillains and all kinds of other characters to reflect their many facets of experience.
There is nothing simplistic about that. I mean sheesh, someone just prompted me for a story about one or more transfolk that didn't mention the trans aspect as part of the story. I didn't even need to make new characters, I already had some in the can. I had two transpeople who already knew each other and were engaged in activities that easily produced a plot having nothing to do with their transness.
It's not about the medium. It's about what you make of it. I'll just be over here looking for "mad, wonderful ideas" that I can shove through the cosmic crack into this world.
