Fascism is generally defined as authoritarian corporatist oligarchy that manipulates people through religion, nationalism and cronyism.
Sending in cronies to dismantle the Post Office and other government institutions is fascist. Sending troops to gas peaceful protesters in D.C. is facist. Stoking racial violence, pardoning criminal collaborators, cozying up to the worst dictators while sacrificing our troops: all fascist.
White nationalism is a crisis because it has the potential to do in America what it did in Germany in the 30s.
Loving our country is not the problem. People who attack immigrants and PoC don't truly love what our country stands for.
