I haven't personally chased this kind of approach because there will be so many judgements that the result won't really be interesting to anyone but the person who created it... but perhaps I'm wrong.
Making an interactive tool out of this could be very useful, because then it could be interesting to anyone who played with it. It will remain somewhat subjective, but at least it could inject some rational analysis into the debate, and has the potential to make some people change / refine their opinions.
