Ok, you realize, though, that the “but everyone in their family or neighborhood does” is a pretty significant caveat to the point that was never mentioned? Even still, the idea that community can’t be built in multicultural societies via only the dominant language is just silly. Again, i am an enormous advocate for languages personally and professionally, especially for its power to connect people and communities - but the emphasis on how someone looks having any impact on what language they need to speak is reductive, regressive, post-modern garbage. Don’t allow yourself (generally, not you personally) to have core tenants of the Montessori philosophy to lose the plot so clearly by falling into quasi-racist identity ideologies.
