You are simply wrong about what the headline assumes, but given that the whole conversation is about the multiple ways in which a text can be read, I have to respect the possibility. Certainly that is what it communicated to you, so I will ammend my original claim: you are wrong about what I believe and what most readers have understood. I DO appreciate that in doing so, you gave us all a very pragmatic opportunity to see how multiple interpretations can arise from a single text, however brief.
I am happy to address what you think would be a better question -- by which you mean the question you most want to ask. I respect the desire, but try not to conflate "best" with whatever you most desire -- it's a misguided approach to pretty much everything.
The answer is that individual politcal aggendas can be surpressed, certainly at the level of conscious supression. It get trickier when one is dealing with less concious desires, but that is true for all of us always, so unless we desire anlaysis which leads to paralysis, we msut press on as best we can, being as self-aware as we can, and leaving as much room for subsequent correction as possible. That's true for SCOTUS and its Justices, and true for all of us as we go through our own lives.
