James Q. Wilson writes:
In the United States, the two groups that most ardently support Israel are Jews and evangelical and fundamentalist Christians. Jewish support is easy to explain, but why should certain Christians, most of them politically quite conservative, be so devoted to Israel? There is a second puzzle: despite their support for a Jewish state, evangelical and fundamentalist Christians are disliked by many Jews. And a third: a large fraction of African-Americans are hostile to Israel and critical of Jews, yet Jewish voters regard blacks as their natural allies.
Wilson examines the differences that many American Jews have with Evangelicals over issues including abortion, school prayer, and gay marriage, but cites a deeper reason for what he characterizes as “Jewish dislike of Christian fundamentalists.”
Though evangelical Protestants are supportive of Israel and tolerant of Jews, in the eyes of their liberal critics they are hostile to the essential elements of a democratic regime. They believe that the United States was founded as a Christian nation and worry about the decay of morality; they must wish, therefore, to impose a conservative moral code, alter the direction of the country so that it conforms to God’s will, require public schools to teach Christian beliefs, and crush the rights of minorities.
