The "YHWH is a daemon" trope, by falling into genetic fallacies, doesn't help anyone because it doesn't explain Christian mysticism nor the Incarnation; becoming an argument disjunct from Christianity. Marcionism. So let's explain the soteriological necessity of the Incarnation.
We can explain Christian mysticism easily: to the degree Christianity maintained pious religion, it received good providence (the gods always prosper goodness). It doesn't mean it was free of falseness, and that falseness is its dedication to a false god.
The false god may not appear throughout the whole religion, indeed we can find parallels between the mystical behaviour of saints and gods, but nonetheless he is present; a kernel of corruption. The daemon crushed Rome and now he crushes all her sons.
