Right there. There's your answer.
Evangelicalism is anti-American and anti-democracy. It is authoritarian and genocidal in nature.
Evangelicals have to suporess everyone else or they can't get to heaven. Some are literally (in their minds) trying to bring about the end times.
This was why the founders wanted that separation between church and state. Because religions make people irrational and patriarchal religions inevitably put their followers on a path on conquest. Because God wills it. Manifest Destiny. The Great Commission. Jihad. Whatever it gets called throughout the ages. It's all the same. 'We are the chosen of God, and so everyone else must be out to the sword'.
This is what hierarchy does. When things get tight and the squeeze is on, those with a supremacist viewpoint will turn on and attack those they see as less deserving or less than rather than tighten their belts and weather hard times together.
In the case of evangelicals, this is in direct contradiction to the teachings of Jesus. Remember the basket of bread and fish? Remember the lesson?
But believing yourself better and more desercib ultinayely means you'd rather slaughter millions, hundreds of millions, than fucking share. Especially sharing equally and equitably.
That's why. And they need a charasmatic strong man to be a lightening rod for that grievance, resentment, and anger. They need that strong man to galvanize the haves against the have nots and lead the slaughter.
We will repeat this cycle until those patriarchal religions are vacated or destroyed.
As a feature of the design, it's inevitable.
Yeshua of Nazareth tried to change that. He was spite executed for his trouble. Today, Christians are clearly happier following the teachings of Paul, an agent of empire, who co-opted the good name of Jesus to redirect a growing social movement back toward the hierarchal design to keep people under the boot of the Roman state. It worked because people are weak and will not give up status and position ober others if they have it.
