They shifted over many years toward Dominionism.
Dominionism and the propserity gospels – both gobsmackingly antithetical to the life and teachings of Christ – became the core values of American evangelicalism. That could only ever have had one outcome: extremism.
Prosperity gospels make wealth and power godly moral aprobations; anything that feels like a threat to that becomes evil… becomes satanic. Dominionism is just what the name implies: "Dominion theology (also known as dominionism) is a group of Christian political ideologies that seek to institute a nation which is governed by Christians and based on their understandings of biblical law." Dominionism becomes the tool by which the properity gospels defend their perceived moral right to wealth and power. Chrisitan nationalism is Dominionism.
