Well, let's not take this thread off the rails, but there are a few problem areas in your response, the central one being the definition of Truth.I don't think individual particular truths (or facts) are constructs as such, but "truth" is a general concept or label for lots of different ideas ranging from scientific to mathematical to religious. Different domains have different particular truths which might not apply to universally or to other domains. Love is another linguistic construct that can indicate a huge range of feelings, ideas, acts and so on which can be largely personally or cultural determined.
For example, it was once thought in geometry that the sum of the interior angles for all triangles was necessarily and universally 180 degrees. And in a Euclidean space this is true. But in general Riemannian geometry, this isn't true.
As for the comparing Euclidean and Riemannian geometries, that's not valid because those are two different systems with different assumptions. Both are valid and being taught in schools and both rely on truth and facts; it was once taught and still is taught.
In fairness to you, you pointed this out but still held it up as an example.
