What are you talking about? Where does it say in the New Testament to kill the Jews or to persecute them?
Factually stating that the Jews killed Jesus (himself a Jew, as are all of the authors of the New Testament minus Luke) is not allowed? Paul writes that the Jews have rejected their Messiah. Yet he states that he himself would rather have his salvation taken from him so that the Jews could have their hearts softened.
You make some radical statements here about the nature of the Scriptures that you cannot back.
“Factually stating that the Jews killed Jesus (himself a Jew, as are all of the authors of the New Testament minus Luke) is not allowed? “
It’s certainly allowed, if not true, but it has led to a lot of oppression of Jews after Constantine the Great converted.
