In my long history in the "Gargoyles" fandom, and my resistance to the notion that Demona will ever be easily redeemed by Angela (as Darth Vader was by Luke Skywalker), one very interesting pattern that I've noticed is that none of the fans who think Demona can easily be redeemed by Angela believe John Castaway is redeemable by "the transforming power of a child's love." This interests me because both of them are two sides of the same coin, and Castaway was designed to be a human parallel of Demona.
Both of them, with the best of intentions, ended up screwing their families over. Demona got her clan massacred and the survivors turned to stone. Castaway paralyzed his brother from the waist down. And both of them said the exact same thing: "What have I... what have THEY done!" Both of them quickly found scapegoats to blame their own failings upon rather than take responsibility for their own actions.
But let's get down to this, shall we? Demona is a mass murderer. As of #12 of the "Gargoyles" comic book, Castaway's worst crime is attempted murder of a police officer, and attempted murder of Goliath... which, at this point, wouldn't be seen as a crime yet, but we all know it is, so I'm counting it. We've watched Demona kill innocent people on screen, and attempt mass genocide. So why do the same fans who excuse her refuse to excuse Castaway?
Well, I can think of two reasons. Two big, round reasons...
Let's face it, she's hot. Hotter than Castaway. But as a heterosexual male, that's definitely easy to say. But there are people out there who will always forgive "beautiful people" easily. Too easily. It's a mentality I hate, but it exists.
Castaway could be seen as "the man." Because, he's part of "the establishment" by virtue of being human, while Demona is part of a persecuted species. Let's face it, his Quarrymen despite welcoming humans of all races, religions and walks of life, definitely evoke something very insidious and very real. I don't think that's the main reason Castaway has no apologists. It might be one of the reasons, but doesn't defeat the argument that there are other, worse reasons. And even if they are designed to invoke the Klan, the Quarrymen are not the Klan. They are a fictional organization persecuting fictional people. Therefore, dislike of them is not that much more righteous than disliking other villains. But even if this is the case, Senator Robert Byrd was a recruiter and leader in the KKK before he left the organization, denounced it, and is even quoted as saying: "I know now I was wrong. Intolerance had no place in America. I apologized a thousand times ... and I don't mind apologizing over and over again. I can't erase what happened." Who is to say Castaway isn't capable of this down the line? It's just as plausible as Demona changing because Angela waves a finger in her face and then hugs her.
But let's say Demona succeeded in either recruiting or cloning a new clan or something, I think she would be using them to spread fear, terror, and violence in her quest for genocide. She would do the exact same thing Castaway is currently doing, she just wouldn't be wearing a hood as she does it.
There is also a tendency among some outcast nerds to identify with non-human characters and consider them superior to humans. But either way, it's not actually believing they are that thing... just that they have enough self-loathing to think their own species sucks, and therefore they identify more with a non-human species because they must be "better." Look at the people who thought of the Na'Vi from James Cameron's "Avatar" as their otherkin. Usually such fictional species are innocent and idealized, and big, bad, Man is the villain, especially in that movie. I have seen some fans who praise Demona for being willing and able to "fight back" as opposed to Goliath who just "stood there and took it," never mind that these are both gross mischaracterizations of what went on.
Bigotry is bigotry no matter where it comes from, and for both Demona and Castaway, we understand where it comes from. For Demona, she projects her guilt instead of absorbing it, while Castaway had this anti-gargoyle dogma drilled into him by the Canmore family since birth. Both know what they're doing is wrong, but neither can face the consequences of their own actions so blame others for their sins. But let's say that Demona is right because the actions of some (not all, but some) humans such as the Hunters and the Quarrymen, and the vikings of the past and others prove that all humans need to be destroyed in order to protect their kind, and any gargoyle who disagrees and opposes her (like Goliath) needs to be killed. Then isn't Castaway right because the actions of Demona (one, but not all) prove that gargoyles need to be destroyed in order to protect our kind, and any human who disagrees and opposed him (like Elisa Maza) should be killed, also right?
