Among the multiplicity of differing opinions, there should be at least a general agreement that there is a multiplicity of differing opinions. Everyone does not agree. Furthermore, most would agree with the proposition that, in some form or another, the differing opinions are mutually exclusive. At least, in some ways, the two contrary positions cannot both be true. While there are those that disagree with my point, their argument is mostly negated by the fact that we disagree on this very point (pettito principi).
