It’s rare for a comic book character to be openly homosexual without the company making a huge, “look how open minded we are” spectacle of it. About 9 months ago, DC Comics announced that its new Batwoman character was, in her civilian identity, an openly lesbian woman. They announced this via press release to major news outlets. This reeked of sensationalism to me at the time, largely because her being openly gay was apparently the only interesting thing about her character - almost as if “lesbian” was a character trait (and maybe it is, actually, but that’s not quite the debate they were shooting for).
This sort of general, all purpose “look at our homosexual character, we are progressive” sensationalism has been common for some time, since about 1991 when Marvel Comics outed their first character (Northstar; who since gone on to become the “gay character of the month” for many writers). It’s actually a shame that this is the most commonly known usage of homosexuals in comics, since on the opposite side of the coin, some writers have actually managed to bring homosexuals into comics in ways that don’t make them seem like circus attractions.
In the pages of DC Comics “Manhunter”, longtime superhero Obsidian is being used as a supporting character, and has been outed in the pages of that comic. This is significant, simply because the character has been around for such a long time, and is not simply a “nobody” hero noone cares about - he’s actually a character that readers were interested in beforehand. Usually, homosexuality is reserved for new characters or characters noone cares about. Also of significance is this isn’t being done in any overt or exploitative manner - he’s simply been shown with his boyfriend from time to time, and readers just put two and two together. They even kiss, which other gay characters in comics don’t get to do. This is actually huge - it shows a willingness to treat homosexuals as actual, three-dimensional people, and importantly, in an industry generally known for slight misogyny and shallow characters.
Sure, the world won’t exactly be changed by how comics portray people. But this is indicative if a general shift of pop culture, and more significantly, a piece of pop culture aimed at young males & adolescents. Rather than treating anyone different as Different, they are starting to be treated as simply existing. I’m a supporter of Memetic theory, which refers to the idea of information and ideas being propagated & spread via cultural diffusion (short version). Presenting these concepts & ideas through pop culture is a very easy, common method of spreading a meme (which can be an idea, belief, clothing or music trends, any idea or concept), whether the author intends to do so or not. The meme of acceptance is spreading.
Another fascinating comic, which came out over 10 years ago, is called Enigma (again from DC Comics). It was an eight issue miniseries, which, underneath the comic book plot trappings, is actually a story of a 20-something man coping with the fact that he’s gay and, ultimately, coming out of the closet. To this day, Enigma remains the most sensitive & thought provoking portrayal of homosexuality that I’ve ever read or seen - and this is in a comic book.
Yes, this same company is responsible for Batwoman, the Openly Lesbian Crimefighter, so we have a bit of a ways to go. But it’s one piece of an overall culture shift, and that takes time.
