Ann Coulter has raised a huge ruckus for defending traditional understandings of Christian origins and Christian evangelism.  Talk show host Donny Deutsch (whom I’d never heard of before) became outraged when Ms Coulter said that the world would be a better place if everyone were Christian.  He accused her of wanting to wipe Jews off the earth, to which she replied, "No, we think – we just want Jews to be perfected, as they say."   Mr Deutsch called her statements “absurd”, “offensive”, “hateful”, and accused her of ignorance and anti-Semitism.  Other commentators soon piled on.

Ann Coulter & Donny Deutsch The critics are the ignorant ones, for what Ms Coulter said comes straight out of the New Testament.  See, for example, St Paul’s discussion of the relationship between Christians and Jews in chapters 9-11 of his letter to the Romans.

N.T. (Tom) Wright, perhaps the leading New Testament scholar writing today, has argued that St Paul believed it arrogant of Christians to exclude Jews from evangelisation efforts.  These passages come from Bishop Wright’s 1991 book The Climax of the Covenant: Christ and the Law in Pauline Theology.

Many Christians have come to agree with most Jews that, since the Holocaust, the church has no right to engage in evangelism towards Jews, since to say that Jesus is the true Messiah for Jews as well as for Gentiles is to be implicitly antisemitic or at least antiJudaic, hinting that Judaism is somehow incomplete. Within scholarly circles, this concern has emerged particularly as the 'two-covenant' theory, which suggests that God has on the one hand maintained his covenant with ethnic Israel intact, and on the other hand has inaugurated the Christian 'covenant' as his regular way of saving Gentiles. In this scheme, Paul is sometimes cast as the hero who anticipated two-covenant theology, sometimes as the villain against whom it makes its vital point.
. . .
[I]t is against Christian arrogance—specifically, gentile Christian arrogance—that Romans 9-11 is explicitly directed. Paul is writing, with all the weight of eleven chapters of theology behind him, in order to say that 'gentile Christians' have not 'replaced' Jews as the true people of God. The church has not become an exclusively gentile possession. Precisely because the gospel stands athwart all ethnic claims, the church cannot erect a new racial boundary. The irony of this is that the late twentieth century, in order to avoid antisemitism, has advocated a position (the non-evangelization of Jews) which Paul regards precisely as antisemitic. The two-covenant position says precisely what Paul here forbids the church to say, namely that Christianity is for non-Jews. To this extent, it actually agrees in form with the German Christian theology of the 1930s—while of course disagreeing in substance, because it denies that Christianity is the only way of salvation.

Paul holds that a deliberate policy of refusing to evangelise Jews is anti-Semitic.

Many other passages in the New Testament are relevant here; I'll cite only two.  After he was raised, Jesus instructed the disciples to “go and make disciples of all nations”.  St Paul called the gospel “the power of God to everyone who believes, to the Jew first and also to the Greek”.

In saying that Christians are perfected Jews and encouraging Jews to become so perfected, Ann Coulter was only repeating orthodox Christian theology.  If Donny Deutsch wants intelligently to engage other religions, he should first learn something about their teachings.
