Conservative Christians to a lesser extent.
That is unfair and untrue. Conservative Christians are the most likely to support Israel and consider themselves part of the Biblical understanding of "Israel" as a definition for "God's chosen people," with whom Christians were "grafted in."
It is liberal "Christians" who don't believe in Biblical truth, who doubt the divinity of Jesus or the divinity of his conception, who turn their churches into country clubs or extensions of the Democrat Party, and who hold Bible-believing Christians in contempt.
