Why say white supremacy when it's fascist. They are not the same thing. Fascism is promising much more change. This isn't the kkk, this is a group trying to overturn representative government, fix elections, persecute critics and opponents, and scapegoat an ever expanding group of others for all of society's ills.
Run by a supreme leader, or group of leaders, they will become mad with power and become worse, and are already starting off from the worst people in the country by character.
