Tumblr lost my original response, so I’ll try to summarize:
There wouldn’t be a problem with you looking back at something you wrote so long ago and critically look at it with your now deeper knowledge of social issues and history. But that isn’t what you were doing. You are trying to make a PROFIT off of it.
Your own description presents a him as a tragic character (did you really say “not all bad guys are, you know, completely bad guys” when talking about a NAZI??) and skims over the fact that any “relationship” you might have in the story would involve a victim and prisoner who can’t possibly give her consent to anything with him. You are romanticizing something deplorable.
I know that as a writer myself, I am careful to make sure anything I post or share as “a good, well-told story” reflects certain values. Technical skills alone do not make a good story; there must be some sort of moral center, or at least something to say beyond simply the actions of the characters alone. You need a premise. From the context of your original post, it seems as if you want to paint a Nazi as a tragic figure who gets “caught up” in genocide. Nowhere do you really mention the prisoner herself. You are contributing to the humanization of Nazis while relegating the actual human victims, twelve million of them, to mere statistics.
The crux: You said “it’s a good, well-told story.” There is no “good” story that humanizes a perpetrator of genocide.
And by the way, that “sticky SJ crap” is the attempted genocide of my people (as well as six million others on top of that).
The fact that you are currently trying to change it so you can still sell it instead of scrapping the thing completely just shows that you don’t have any concept of how wrong what you are doing it. Want to write about how people are driven to do horrible things? Don’t make your protaongist a goddamn Nazi.
