So when are one of you actually going to write a story with a Nazi protagonist?
Seriously, this topic comes up (Trolling or otherwise) like every six months or so, and a lot of shit gets said, but nothing ever comes of it.
If you're going to write one, just do it already. Because if it gets brought up in the forums the only thing that's going to happen is a lot of debate/insults/lulz and nothing will get done.
The end result of your writing will be judged accordingly. If it sucked, we'll be sure to let you know. If it didn't, then you'll find that out too.
And seriously, just go with a regular Nazi, rather than Hitler. You'll give yourself more writing freedom of what can happen to the character in the end (Again, dead in battle, war crime execution, escape to South America, pardon for making a deal, etc) and you can still do all sorts of fucked up shit. If anything, you'll get the chance to directly participate.
