Making an editorial suggestion is not akin to burning books, not the least bit. If you are a journalist, you don’t get to call your editor a “Nazi” because she decides to not publish your story.
This comparison is stupid and offensive, it trivializes what the Nazis actually did for a cheap and inaccurate insult.
Don’t insult at all, if possible, but if you must pick something less stupid than “Nazi”. Call him “ass”, “narrow minded”, “censor”, “idiot” or whatever, I wouldn’t care at all.
