“Evangelical athiests”? I hate that nonsensical misnomer:

WEBSTERS:
evangelic -ik\
Function:
adjective
1: of, relating to, or being in agreement with the Christian gospel especially as it is presented in the four Gospels
2: protestant
3: emphasizing salvation by faith in the atoning death of Jesus Christ through personal conversion, the authority of Scripture, and the importance of preaching as contrasted with ritual
4 acapitalized : of or relating to the Evangelical Church in Germany boften capitalized : of, adhering to, or marked by fundamentalism : fundamentalist coften capitalized : low church
5: marked by militant or crusading zeal : evangelistic

It is totally unfair to call atheists evangelical. Even if you mean it in the most secular possible sense, you are saying it evoke its vernacular connotations.
