JY - Do you accept that your OP is an attack on fundamentalist Christianity?
Biblical literalism demands belief in impossible things and is very easy to destroy. But that ignores the millions of christians - and people of other faiths - who find utility in religion without needing to lie to themselves.
Religion is nothing like Mein Kampf is it? National Socialism was founded on the doctrine of Aryan racial superiority. There is absolutely nothing positive that can be retrieved from that. Christianity incorporates a lot of useful memes that go beyond the dictate that 'murder is wrong'.
Have you read Jonathan Haidt's book The Righteous Mind? There is an interesting chapter titled Religion Binds and Blinds in which he looks at the evolutionary roots of religion and the way it enabled group cohesion. I'm still not sure how we replace that in a post-faith society. So far we seem to have come up environmentalism and intersectionality. I'm not in any hurry to see the end of Anglicanism and Universalists.
Full disclosure - There is no supernatural realm and I would rather stick pins in my eyes than attend church. I'm genuinely thinking out loud on this. Dawkins sees all religion, however benign, as a mind virus. Hitch (god rest his genius soul) said that religion belongs to the infancy of our species. Harris allows for a distinction between more and less harmful religions but fears that mainstream religion facilitates dangerous ideas. You seem to see all religion as akin to Nazi dogma or a rotting carcass.
I'm really not convinced.
