You don't have to be German or yell in speeches to be a fascist. You can be American and desire to be a dictator. Trump is showing the signs of desiring to be a dictator.
1. Declaring internal war against minorities.
2. Declaring external war against others.
3. Declaring war against the mainstream press.
4. Allying with other dictatorships like Russia.
5. Campaigning after the eleion.
6. Denying the facts of the election.
It can happen here. It has happened in the past. The past is prologue to the future.
