I find this to be dubious - the Constitutio Antoniniana was in 212 and mostly for expanding the tax base, likely because Rome wasn’t doing too hot. The fact that the didn’t explicitly ban race mixing was probably because Rome was mostly racially homogenous. Expanding citizenship because they were desperate for tax revenue doesn’t sound like race-mixing had anything to do with it, if anything it was probably that along with the expansion of Christianity that it even became something to have to address.
But even with that, if you can find any actual dates on Christians outlawing racemixing anywhere near that time, as far as I’m seeing it wasn’t until like after the 1200s that that stuff started picking up, so there’s a 1000 year gap there.
Also, just to take this down to layman’s terms, do you really think that people who were tribe first had this issue? Do you really think that pagan Germans were actually having a problem with their women fucking niggers and Jews? Like what other than Christianity would have given people the idea that “hey man as long as you believe in the same thing race isn’t real”. It doesn’t pass the smell test.
