Wasn't I talking politely and respectfully?
Formally yes, if you mean that you didn't curse or something like that.
But what you say is extremely cold and harsh, and sometimes humiliating. This you phrase
There's a huge difference of the answer I'll give to a Gentile and an answer I will give to a Jew. "Prejudice"? Didn't expect to hear this word from a JTFer.
combined with the fact that you said that Gentiles don't have the right to criticize the Jews, even the evil ones, shows that you treat the gentiles as subhumans, at least it can be interpreted so.
You can talk so only to enemies. It is very injust to speak so to those who support the Jewish people and state. But the most important, it harms the Jewish cause, specifiaclly it incites
additional hatred of some antisemites to Jews.
