Certainly, in the article I'm making broad generalizations about both conservative and liberal Christians. All concepts overgeneralize, though, depending on your level of interest. So the question is only whether the broad patterns obtain too, or whether the subdivisions undermine the higher-level distinction.
Are conservative Christians more likely to have theocratic ambitions than liberal ones? It seems so. There's cultish tribalism on the liberal side, too, mind you, as in the case of Wokeness. But that's not a Christian phenomenon.
It's interesting that you point to a social Darwinian purpose of competition within conservative circles since that's consistent with my take on conservatism (link below).
There are layers in the gospels, not all of which likely go back to the earliest Christians. If those Christians followed the later, pro-Roman advice, Jesus would hardly have been executed on political grounds that called for crucifixion. The rigmarole of scapegoating the Jews who supposedly forced Pilate's hand was an elaborate way of ingratiating Christians with Rome after the Jewish-Roman Wars made the topic of Judaism toxic.
So yeah, there's conjecture in reading the tea leaves of the gospels. But there's conjecture in every telling of history when the evidence is paltry, as it often is with respect to our knowledge of ancient events. The Christian revenge fantasy was that Jesus would return in force to finish what he started and to smite the nonbelievers. In the first century CE, the Roman Empire could hardly have been characterized as faithfully Christian or poor in spirit.
