My main point of disagreement is that it's sometimes hard to say if some evidence is "for" or "against." It might also be subjective. Or it might be ___, for which I don't have a word, but an example would be General Relativity as it relates to Newtonian Physics.

I imagine you could propose evidence as "for" or "against", and then the discussion steps down a level to the quality and direction of the evidence.
This would all need to be hierarchical, and what I call "evidence" may really be a "sub-claim".
