Yeah, when you ditch an inferior moral system for a superior one, you don't have catastrophic results.
But when you ditch a superior moral system, for an inferior moral system, you do get catastrophic results.
Kind of funny how that works out.
Again with your conclusion assuming your premise is correct. No, Catholicism is not a superior moral system
with regard to ideological conflict, because the obsessive logical formulations to connect absolutely everything in the scripture together into as cohesive a worldview as possible creates points of failure on things that
do not fucking matter or are outright
bad like having a singular worldly institution as sole moral arbiter.
And the earlier forms of Christianity that displaced Roman religion were an utter clusterfuck. Again, street riots over theological minutia, whether it be the contents of the Eucharist in terms of transubstantiation or the internal nature of Christ. Yet the churning mass of barely-related post-Judeo-Stoic mostly-nonsense did not create
catastrophic results like the churning mass of barely-related post-Christian mostly-nonsense, because
people were used to questioning ideology.
There was a healthy ecosystem of varied baselines to what you thought was right and
why you thought that so and established customs to handle different moral standards, things Christianity
went out of its way to be rid of. And without those, when the Catholic Church inevitably discredited its moral system for huge swaths of Europe by being corrupt elitist cunts, you got nonsense because people couldn't behave themselves dealing with those of minutely different framework for mostly-identical moral standards, let alone the coming shitshow of post-Christian utopians deriving irreconcilably different frameworks for wildly divergent moral standards.
