Truths are always lurking, even in politics and court rooms. Though such environments are not optimized for truth gathering. Despite the constellation of subjective filters to fuel disagreement i.e., memory, interpretations, biases, faith, there is always the possibility that with enough hard work one can draw out a fact of the matter. Disagreement is moot, including that of political parties, when or if nature/math/truth says otherwise. My two cents if that.
