Its Right wing authoritarianism and social dominance orientation
People who feel they are the ‘default’ americans (white, christian, patriarchs, native born, cishet) feel they are the default Americans and entitled to rule.
America is rapidly becoming more multicultural and secular.
The % of Americans who are white is going down
The % of Americans who are chrsitian is going down
Feminism is growing rapidly
The immigrant population is going up
Alternative lifestyles like LGBT are going up
This makes the ‘default’ americans feel they are losing control over power. Also they are terrified that once they are the minority, that they will be treated the same way that they treat minorities when they are in power. They are terrified they’ll be treated the same way they treat black people, women, muslims, etc when white christians are the minority.
In 1970 about 81% of Americans identified as white christians. Its currently around 40%, and among Gen Z only about 27% identify as white christians.
People high in RWA also feel the world is a dangerous place full of dangerous out-groups (muslim terrorists, latino gang members, black people in the inner city, sexually predatory transgender women, etc). They feel they need a strong military, a strong police and large amounts of guns in civilian hands to keep society safe. They see the left as defunding the police, weakening the military and passing gun control, making them helpless in a dangerous world.
Also people on the right side of the political spectrum more strongly support the concept of a behavioral immune system. To them diversity isn’t just a novelty, its an infection or sickness in the social body that is going to weaken social cohesion and cause social collapse.
Donald Trump is their great white hope of bringing America back to the 1950s when white christian men ruled and everyone else stayed in second place.
Donald Trump can rape as many children as he wants, as long as he says whites are better than POC, men are better than women, christians are better than every other belief, etc Trump will continue to have a basement support of 30-40% of the country.
