Alright one of my conservative expositions.
One thing we should remember, having a citizenry with a strong faith has been an effective counterweight to government at times. Under Soviet rule Christianity did a lot to subvert Marxism.
although I could make the case that Islam is even more effective at thwarting Marxism. The Soviets had a fun time in Afghanistan, did they not? [/snark]
What matters more is that the political leaders have some moral compass. Buddhism (which puts little emphasis on deities of any kind) at its best is better than the watered-down Christianity that a Mammon-worshiping Christian-in-name-only like Donald Trump has. Sure, Trump knows how to appeal to Christian identity and affiliation... big deal. Don't forget that fervent belief in God is more the norm in the Islamic world than in the heavily-secularized West. (Indeed, were I to pose a scenario in which the Nazis had taken over most of the West, then I would expect Islam to be the deliverance of the West from the amoral, dehumanized idolatry of Blood and Soil and gross enslavement of Nazism. Better Muhammad than Hitler, wouldn't you say?
I could make the case that there was nothing wrong with the German people of the Hitler era that Judaism wouldn't have solved. I say this as someone who is about half German or Swiss in ancestry.
I could argue that doubt does more good than does faith in something evil or empty. People often had resolute faith that slavery was the optimal means of solving problems of economic production. If I hear some voice claiming to be God that tells me that it is acceptable to have sex with underage children, then I had better have enough doubt to reject the dubious authority of such a voice.
As a near-agnostic I find that I must take more responsibility for my actions. I reject the concepts of original sin and cheap grace because those erode responsibility to Humanity.
But it is not all the same faith. But here's the irony -- Martin Luther King and the typical KKK fascist believed in the same God and the same Jesus, and recognized the same Holy Scripture.
