I will never tire of people who do not grasp linguistics trying to be pedantic about words.

In a living language, words mean whatever people currently use them to mean. This is how "literally" literally doesn't mean "literally" anymore. Most people use Nazi to refer to both 1930s German National Socialists and modern day white supremacists. Therefore, that's what it means. English is not a dead language like Latin, so stop trying to treat it like one with regards to this one word. It just makes you look like a Nazi.
