I admire the work of the FBI against hate groups and extremists. However, one only needs to look at their work against BLM or the Civil Rights Movement to see that they are part of the same structure.
Workers unifying across social divisions is the greatest threat to oppressing the people. It is the most powerful method we have of gaining material freedom and our most basic human dignities, regardless of ethnic identity.
Some of our most deeply exploited white citizens are convinced that they have it better than others while they experience collapsing infrastructure, life on government benefits, prescription epidemics, growing government overreach, and erosion of their working rights. They also make up the heart of white supremacists and domestic extremists, while more fortunate liberal territories are convinced to despise and separate themselves from their fellow workers.
In short, our nation is divided by hatred and the result is a populace that is easier to control, oppress, and economically exploit. Overcoming this hatred and unifying is the key to securing our future and basic liberties from corporate and government authoritarianism.
