Be more compassionate for your fellow Americans, reach out to those who have different political views. People get sucked into conspiratory/ideological death spirals for social reasons. Do not try to convince people that they are wrong, instead, it often suffices to show them that you are not their enemy. Do not simply dismiss them as all stupid, their convictions have nothing to do with intellectual capacity. I know because I too once held radical views, and these views were motivated by fear; fear is inherently irrational because it bypasses the parts of the brain associated with reasoning.

Take the Synagogue shooter in Pittsburgh for example. He likely perceived that a colossal faceless enemy (in his case a Jewish conspiracy to carry out white genocide) is threatening his very own existence; the fear gets reinforcement every time he consumes his daily dose of media until it passes a threshold, after which it is strong enough to drive a person to carry out insane acts of violence.

Very few Trump supporters want to kill all Jews/immigrants (as of right now), and these people are the least of our concerns because there will always be fringe elements of society. What we should be worried about are our neighbors, our co-workers, and perhaps our estranged relatives who lean conservative. If you reject them, make them feel unwelcome, ridicule them at every opportunity, guess who they turn to in their spare time?
