A combination of selective memory, cherry picking and other logical fallacies can lead to cognitive dissonance. Things like nationalism, patriotism, propaganda and public relations can be used to place people into that state without them realising it. That is the power of advertising (ready about Edward Bernays and Anna Freud if you want to be really frightened).

Capitalism, communism, climate change, climate denial, racism, LGBT rights, reproductive rights, states rights, federal rights, debt, money, free markets, religion, atheism, healthy foods, unhealthy foods, pollution, consumerism, environmentalism ... you and I are wrong about one of these things. Statically we have to be. At least one of our core beliefs about society will eventually be proven entirely wrong at some point within the next century. Keep that in mind the next time you get into a political argument.
