You DID ask what we thought of the story. If you don't want people to say what they think of the story, then don't ask about it.
The fact that you're half-Jewish and live on a cliff is not in the story. That needs to be IN THE STORY to work with the story. No one ever assumes that just because a piece of fiction is written in the first person that the narrator is the same person as the author. ANd even if he is, that the fact will be the same as the real life. You've never really encountered dinosaurs, nazi or otherwise, so why should we assume you haven't changed anything else. Those descriptions need to be in the story.
And really, you need to just shut it about Sprig not liking your story on the basis that it makes light of Nazism and the Holocaust. REally. You're being an immature jerk about it, acting like a 5 year old. Just because someone makes a different value judgement than you does NOT mean that they are reactionary and misguided.
