Why are you using the term “nazi” to refer to people who are “needlessly strict”?

Because it is an acceptable use for such a word. You can find the fallout from one of my uses of it on this linmagazine.co.il page (in Hebrew) (“And what does it have to do with anything? Did Hitler use Linux?”). I didn’t stop using the word “nazi” afterwards, and also see the post “The Grammar Nazis Conspiracy” on my personal/philosophical blog.

Many people treat the Nazis/Hitler/Holocaust/World War II issue with too much “holiness”.

Another recent use of this in my works is in featuring Chuck Norris and Summer Glau on The Muppet Show as Grammar Nazis (with a capital “N”) who undergo a gradual Catharsis and become benevolent people.

Furthermore I should note that using "nazi" like that actually underlines the main reason which caused the deterioration of the Nazis in Nazi Germany due the fact that they were too insistent on being strict and avoid breaking or bending the rules, or voicing any antagonism towards Nazism there. This made them into tragic victims who accepted their fate of death and stagnation instead of being action heroes or “hackers” who constantly bend the rules, challenge norms, and don’t accept their fate:

Also see "just following orders" or the Nuremberg defence, with which the "I just work here" attitude is not different.

Why do you mention Hitler, Nazis, etc. in some of Your Writings?

I found it suitable to use it for them, so I did. For the record, my grandfather lost most of his family during the Holocaust, and so I cannot be accused of misusing such facts. Steven Spielberg whose parents are Jewish Holocaust survivors, also featured the Nazis or Hitler in many films (notably the Indiana Jones trilogy), so if a fire has caught the Firs…
