"Ethnocentrism comes naturally when we identify with a group, but authoritarian followers are profoundly ethnocentric. Whereas some people will deliberately expose themselves to different ideas, experiences, cultures to avoid living in an “echo chamber,” followers want to live smack dab in the middle of one and are glad to do their part of the echoing. Surrounding themselves with people who agree with them, clapping together, chanting together, cheering together, and marching together is convincing evidence for them that their beliefs are right."
