Origins: In the mid-2000s, the Bush administration refined its broadly titled "War on Terror" campaign to the "Fight Against Islamofascism." This transfered the stigma of the 9/11 attacks and that carried by our enemies in the Middle East from tactics (e.g., terrorism) to policies (e.g., a Muslim caliphate). Since politically-active Evangelicals seek to at least partially theocratize America, the term "Christofascism" appeared to take advantage of the Republican rhetorical realignment.
One uses the term perjoratively when calling someone else a Christofascist. It inherently accuses its object of disloyalty to democracy; it attempts to evoke the feelings of hostility towards Middle Eastern terrorists and transfer them to Evangelicals.
When discussed generally, Christofascism is a bold label for political Evangelism but does not sling as much mud as the former usage.
James: Like every other Christofascist, Andrew, you want to replace our Constitution with the Bible.
Moderator: Jennifer, I know that you are working on behalf of the Socialist candidate, but I'm wondering what you expect will be the ground effort that Evangelical Republicans make this year on behalf of the Republican candidate's campaign?
Jennifer: The important thing to remember about Christofascism is that they only participate in party politics when they believe it will advance their specific agenda. If the Republican candidate only campaigns on the economy and national security, the Christofascists will not go the extra mile in terms of campaign support that they tend to go when the nominee talks about abortion, public prayer, and gay marriage.
