Inventing Reality

I typed out a lot of shit. As I typed it out, I understood that ideological systems as widely spread out as Christianity are so complex that I don't have a proper framework for analyzing it. Imma still leave the comment I typed out in case you care.

Christian philosophy is whatever it needs to be to fit the society that birthed it.

You ain't going to see me argue against the base-superstructure model. But Christianity is not "homegrown" in much of the world. It spread internationally and was imposed in many parts of the world. Thus, names, myths, ethics, metaphysics, legal theory, culture and many characteristics of Christianity carry across multiple societies, classes and mode of productions.

This can come in the form of concrete policy criminalisation of LGBTQ people in post-colonial nations, or more subtle philosophy such as the christian outlook on things like "sin" and "virtue", or on "purity", "martyrdom", or the essentialism, or eternal spirits and so on. Not all that is unique to Christianity, but Christianity does have its own take on those things.

I would say could be more easily explained as a racist imperialist mindset

It is both. The "civilizing mission" style of justifying imperialism started with the justification of spreading Christianity first.

since you’d have to somehow claim the naked racism of Dawkins somehow has a similar origin to the Christian abolitionist groups of the American south pre-civil war

The ideology of the ruling class also becomes the ideology of the underclass through indoctrination. This creates a class divide/tension in that ideology, even though it is technically the same ideology. So it is not unusual for ideological similarities to appear in vastly different class circumstances*. It's part of what makes politics so frustrating and confusing if you look at only ideology

*that's not to say that those groups believe in literally the same things, although it's not as if Richard Dawkins claims to be against abolition.
