Trump and his likes try to win people with fear, hatred, anger, and pride for one's birth. We need to put something stronger against that: Confidence, friendship, joy, and pride for one's achievements (those in the past and those in the future). Not in a hippie-kind of way, though, but in a "real man" kind of way, such as this:
"Follow me, and we'll build a better world. One where there is a good place for everybody. This is a great task, but let us not forget to have a party now and then along the way. Trust me to lead you, and we'll build not walls, but roads, hospitals, factories, parks, spaceships, and wealth for everyone!"
Of course, you then need a leader who actually delivers on such promises.
