I am honestly curious, is English your first language, and may I ask where you were born and educated?
If you and I were in a room, and it was apparent you were an American as am I, and educated in the US, and you used phrases like the 'the Jew community', yes, that phrasing is an indicator of anti-semitism as much as either of us tossing around the n word might be an indicator of bigotry against blacks.
And I would say that is probably true for most countries where English is spoken as a first language.
When you write "Yeah, but his victims were not rich jews" you pretty much state his victims were rich Jews and if not for that, we might not hear about the Holocaust.
It is clear the vast majority of the victims of the gas chambers were very far from "rich".
Israel of course has very little to do with why we remember the Holocaust. But if you don't understand why we study WWII and the Holocaust apart from "rich Jews" again I have to wonder, honestly, where were you born and educated?
