"The true motivator for Christian nationalists is not actually their religious beliefs but the preservation of a certain kind of social order, one that is threatened by racial minorities, immigrants, and Muslims." If that's the case, pointing out their hypocrisy - their political positions and support for Trump vs. the actual teachings of Jesus - won't have any impact, because they care more about their social order than they do about their faith. Evidently they don't really care much about Jesus.
