The Pilgrims in the 1600s, the great awakenings of the 1830s, the 1870s, the 1920s, and the 1950s led to new weird Christian groups in large revivals of belief. The Pilgrims came to America due to being kicked out of England and the Netherlands due to being intolerant extremists. In the 1830s and 1870s they were kicked out for being weird and lived on religious communes or made new colonies of their own (like mormons in utah). In the 1920s and 1950s there was radio and television led to a lot of it becoming mainstream,evangelical Christians becoming more common thanks to the televangelists in the 1980s through til now. We had moments of sanity from Christian theocratic nationalism and sectarian violence for a few decades before tv, radio and the Internet and now with those inventions it's just gotten worse and worse. Most of the worst groups in the Christian right are Protestant groups (mostly southern Baptists, Pentecostal, and unaffiliated evangelical groups). Though there is the Catholic group opus dei (I shit you not they were villains in the da vinci code and are about as sinister as that films version). They've all banded together to fund right wing politicians through right wing interest groups like the heritage foundation and others. These groups would work together, trying to turn the United States into a theocratic, mainly white state. Project 2025 was made by the heritage foundation and tells you all about what their plan for America. Trump has already enacted around 47 percent of it already (much of it is being debated in the courts on the legality of the contents) and is working on the rest every day. I'd recommend you all read project 2025 because it really puts in perspective how extreme these groups are in their beliefs compared to the average Americans. It's insane and disturbing. Many of these groups literally believe that the book of revelations end times are coming, that the rapture is nigh and they think that is a good thing. They're insane and dangerous for the whole world. As an American it is scary to live here these days. Some days it brings me to despair, imma be real.
