What is Antiracist Heaven?

The opening clip is from the 1946 film, "A Matter of Life and Death" which gives the idea of a fairly mainstream perspective on Heaven for that time period, a vision of Heaven where everyone has a distinct cultural identity and a Heavenly council would care quite a bit about a romantic relationship being people of "good stock" same race, and even same nationality preferred, viewing relationships of people too distant nationally or racially as questionable. However, this movie is still for non-white immigration for America, so while in 1946 Western viewers could accept some amount of American immigration propaganda, they did not think that Heaven would be particularly open to mixed relationships. Learning about that pro-immigration stance though I did find that one of the main people working on the movie was a Hungarian Jew. Anyways, more a view of where Western audiences were largely thinking about Heaven back then. How about now? Seems that as Christianity goes through constant changes, pushed by political forces, that the moral expectations of Christianity change. So are we sure about the antiracist expectations of Heaven? I for one would say these expectations, as they are understood today, are not reasonable for history, for modern nations outside of the West, or in scripture.
