the only difference is the lack of a german language.
And the lack of anti-semitism
And the boundedness of their expansionism
And many other differences.
Expand your fucking vocabulary, rather than reaching for the only genocidal analogue you can think of. There has been more than one genocide in history, and you do dishonour to the victims of any one by using its name to describe something different.
I am defending the truth, and you’re too committed to your untruth (whether mistake or lie) to accept that someone can do that while otherwise sharing your beliefs.
“Semitic people” is not a category that is used any more; it could refer to “speakers of Semitic languages” but is completely obsolete for referring to ethnicity. And besides, Zionism, or the current Israeli government’s version of it, is not murdering Palestinians because they belong to the group of people once referred to as “Semitic” because that would include all Arabs and all Jews as well as several other people. Genociding people who belong to a certain category doesn’t mean you’re anti- that category. For a trivial example, they are genociding human beings - does that mean they are anti-human? Obviously not.
So, if anti-semitism does not refer to hatred for the entire group of “Semitic people”, what does it refer to? Well, it has some history being used more or less in the way you apparently believe it still is used, but in 1879 a chap called Wilhelm Marr wrote a pamphlet in which he used Semitismus interchangeably with Judentum, and Antisemitismus as a synonym for Judenhaß - Jew-hatred. That is what it has meant since.
There is only one reason I can think of beyond blinkered stubbornness that you could possibly want to associate the Nazis and antisemitism with the Israeli government, and that is out of some pathetic sense of irony, that it is somehow poetic that the Jews have become what befell them in the early 20th century. That is poetic, but poetry isn’t truth, and disregarding the suffering of Jews at the hands of the real Nazis by calling what Israel now commits “Nazism” belies a disregard for Jews as a whole which is at best distasteful and at worst abhorrent.
You are letting yourself speak in a prejudiced way because of your opposition to the genocide that Israel is carrying out. How can you say “grow up” when you let that happen? No population deserves to be murdered the way Israel is murdering Palestinians - but no population deserves to have its past suffering mocked in the way you mock the suffering of Jews by calling Israel Nazis.
