Nothing is perfect. Achieving communism won’t end all prejudices overnight, the revolution will need to continue essentially forever.

Of course, but that's not the point I'm disputing. Anarchist Catalonia was imperfect, but I regard it extremely highly as a model for examination and emulation in terms of a modern conception of socialism or communism.

Many white people call payback barbaric, but after actually reading what indigenous people have to say about it, I like it better as a punishment for crimes than the white prison-based “justice” system.

... that's an extremely concerning position. That's what leads to 'honor societies' pretty inevitably.

If you’re hesitant to comment on indigenous societies,

I'm not hesitant to comment on them. I'm hesitant to regard the concept of 'primitive communism' as positively connected to modern conceptions of communism, given the past ~100 years of anthropology, political philosophy, and sociology. Societies develop tools and systems according to their own circumstances and needs; 'primitive communism', again, acknowledging my dislike of the term, is not reflective of a society that has developed modern ideas of justice and equality, but of societies which face issues entirely different from modern ideas of justice and equality.
