I’m interested in concrete advice about how to resolve this problem in a real argument (which I think you don’t quite provide), but I’m also quite interested in the abstract question of how two people with different ontologies can communicate. Normally I think of the problem as one of constructing a third reference frame (a common language) by which they can communicate, but your proposal is also interesting, and escapes the common-language idea.
