Color me naive... Am I the last person in the world to discover that Wonder Woman is a lesbian? And now Batwoman too?

A little research uncovers much debate about Wonder Woman’s sexuality. Is she or isn’t she a lesbian?

Don’t limit your opinion on this one link. Do a search for “Is Wonder Woman a lesbian” and let me know what you think.

And very surprised I was to discover a special lesbian universe for Bat Woman as well…

“The Powers That Be are pretty good these days about letting you choose to make a character of your own design homosexual or bisexual, but the closer you get to an established character, the harder it becomes,” Grayson said. “And although I sympathize with that decision in many respects—it’s not fair to retcon an established character just to make a socio-political point—the problem with that policy is that, for the sexual identity issue to have weight in the world of superhero icons, the so-identified character has to be an icon.”

Really? Should writers set out to promote any sort of sexual identity at all in their comics? Should they tamper with established superhero icon sexual identity or just leave it alone and let the reader assume what they will. Why wouldn’t they choose to create an entirely different character to promote a specific sexuality agenda, instead of hijacking historical perceptions to serve a serreptitious campaign?

Why not just come out with a new comic with a new homosexual character and see how it flies on its own?
