It's impossible for a single school system to represent all those views. We're still facing those issues, and gradually Americans are coming to see that a single educational system is not going to work. Many fundamentalists seem to hold two views at once. On the one hand, America is Babylon and under judgment. On the other hand, America is Israel, God's chosen nation.
Fundamentalists are willing to take a stand, and that's often been a difficult thing to do.
If you let culture make tolerance the preeminent virtue, pretty soon you won't have anything else. And so it's good that there are Christians who have said we need to draw a line somewhere. In his early years, Billy Graham was embraced by fundamentalists. But at his 1957 New York City crusade, he spoke well of mainline Protestants and Roman Catholics, and he didn't discourage new converts from attending non-fundamentalist churches. Graham's more open stance toward other Christians was too much for fundamentalists, who have refused to fellowship with him since.
