You are exactly right - the very non-acceptance of Christ by Jews as the promised Messiah - and hence of the New Testament - is what separates Jews and Christians. Obviously.
But my saying what I did, and my belief that (on a related issue) the only way to salvation is through Christ, does not make me anti-Jewish or intolerant or anything of that sort, anymore than a Jew's claim that I am following a false Messiah makes him anti-Christian or intolerant (I know you have not accused me of such, and I appreciate it, but others have).
But I will try to persuade, and barring that, at least enjoy a civil discussion. And I take no offense at Jews evangelizing their faith.
Again, thank you.
