America is not mired in a culture war. In reality, today's Republican Party and larger "conservative" movement are waging a fascist war against multiracial pluralist democracy and human freedom. Ultimately, to not understand how the so-called culture war is actually a fascist war against American democracy is to almost ensure being rolled over by those evil forces.
Many political observers point to Pat Buchanan's infamous 1992 speech at the GOP national convention as the beginning of the so-called culture war in America. However, the roots of this fascist and authoritarian campaign are much older: Jim and Jane Crow and white-on-black chattel slavery, genocide against First Nations peoples and white settler colonialism are America's native forms of fascism. When located in the proper historical context, neofascism and the Age of Trump are properly understood as being but the most current manifestation of much older birth defects in American democracy and society.
