The Call, “In the Name of Humanity, We REFUSE To Accept a Fascist America!” says:
Fascism foments and relies on xenophobic nationalism, racism, misogyny, and the aggressive re-institution of oppressive “traditional values.” Fascism feeds on and encourages the threat and use of violence to build a movement and come to power. Fascism, once in power, essentially eliminates traditional democratic rights. Fascism attacks, jails, even executes its opponents, and launches violent mob attacks on “minorities.” In Nazi Germany in the 1930s and ’40s, fascism did all these things. This is where this can go. And yes, Hitler himself could “talk graciously” when he felt it would serve his interests and lull his opponents.
And by any definition of fascism, the incoming Trump regime would be a fascist regime.
