I heard of one or two of them, but the question is not that the Evangelicals are not smart but that their theology, by definition anti-clerical, is not a sufficient resource to combat secularism.
It was the politicized clergy and hostility to Republicanism by the Catholic Church that caused said Church to be hated by many American citizens for years. It was only through assimilation (and adaptation of American Republicanism) that Catholics became accepted.
Clerical-influenced governments and quasi-theocracies are as hostile toward our Republic as communism and Mohammadism. Some of us prefer Washington and Jefferson's America over Salazar's Portugal and Franco's Spain.
What does that have to do with fighting secularism? That is a strange response to my comment.
