As there should be no such expression as anti-fascist ever needed, (a person who disagrees with fascism is just that a person, it is a default to be anti-fascist), all Donald needs to say is,
“All people should be treated equally. Equallity is a basic right; a basic right which effects everything. Anyone who wishes to treat some types of people worse than others is evil, evil, not just wrong; evil.”
As soon as people of influence start saying so then there will be hope for the world.
This effects everything.
This world is filled with people who have to be treated equally.
