1. Internet comments shouldn't be taken seriously. Many of "those" people perhaps are not even christians.
2. bolded - I would have to respectfully disagree with you.
Evangelicals so strongly support Israel. The answer is that a significant majority of American Evangelicals believe that the Abrahamic Covenant is still in force.
The Abrahamic Covenant (Gen. 12:1-3) says, among other things, that God promised the land of Canaan to the Jews forever. A significant majority of American Evangelicals believe that God is a keeper of His promises and that the "Promised Land" belongs to the Jews in belief and unbelief, in obedience and in disobedience, forever. (It is an unconditional promise, with no time limits or conditions.)

Why Do So Many Evangelicals So Strongly Support Israel?
So yes, Evangelicals most definitely support Israel and the Jewish people.
Many Evangelical Christians believe that the Jewish return to their current homeland in the twentieth century was, and is, a fulfillment of biblical prophecy.
The mutual admiration between Israel and the United States is hardly a recent phenomenon.
Let's face it, The same U.S. military forces and programs that help protect Israel from Iranian missiles and Islamist terror groups also protect Arab oil-producing states. But if America’s role in securing the oil were to wane, it would be harder to ignore the cost of defending Israel, and that might force Jerusalem to become more self-sufficient.
