As I see it, beliefs divide people and lead to authoritarian tendencies: in a "contest of power" (M. Foucault) between beliefs both sides see their very sense of themselves and their view of life itself at stake. Compromise is impossible. Defeat is unthinkable. The only acceptable outcome is total victory by one side or the other (unless a stalemate drags on long enough for exhaustion to result in an acceptance of co-existence). That was the basis of the religious conflict that plagued Europe for centuries (and has been revived in all manner of 'fundamentalist' religion) and it has been the basis of ideologically based conflict in Modern times.

To my mind, the people who are getting swept up in this new brand of 'conservative' that Trump represents are not ideological--or theological. It is pure emotionalism. They have developed an irrational hatred for political liberalism and liberals. For them, politics is about nothing else. Any reference to any belief--other than the belief that liberalism is pure evil--is merely a rhetorical tactic.
