No, I'm not.
> Substance can't be mapped onto reality without prioritizing values and deciding accordingly.
That is a syntactically-valid sentence but I have no clear idea what it is trying to communicate relevant to the discussion.
> The belief of individual liberty is shared throughout America
The idea that there is a thing called “individual liberty” that is to be valued is broadly shared. What that label actually means is not a product of such a broad consensus. This isn't a matter of “how to achieve individual liberty” being a matter of disagreement (that is true, too, but a different issue) but the fact of what it means to say “individual liberty” being a matter of disagreement, with mutually incompatible views as to what that means.
> Your last point is in alignment with everything I've said before
No, it's directly opposed to it.
> We have the same over arching goal (happiness), we just disagree about how to get there.
No, that's what you said. What I said is that Alice has the goal “Alice should be happy” and Bob has the goal “Bob should be happy”, and these are not the same goal, and may (depending on what actually concretely produces happiness for Alice and Bob, respectively) may be mutually incompatible goals. And when you scale up to hundreds of millions of people with goals of that style, absolutely are, in very many cases, mutually incompatible goals.
This is not at all a matter of dispute about ideal path to a shared goal, because the goal is not shared. The language Alice and Bob use to describe the goal might be shared (each might say “I want happiness”), but the actual goal is different, it's just the differences are elided in the casual description.
