Seeking consensus on public issues rather than victory does not debase your point of view, but rather makes it more valuable. There is no contradiction between being a forceful advocate and a good-faith searcher for middle ground. In fact, only by filling the first role can you perform the second.
All this of course presupposes rational humility: acceptance that, with all the world’s unknowns and the limited ability of humans to learn and understand, we can all be wrong about the large questions and probably are most of the time. All we can do--but this is a lot--is bring to the table our experiences and ideas and the beliefs that flow from them.
So whether you fail to effectively express your views through unwarranted timidity or quash a different perspective through excessive aggression, your diminishing the collective conversation. We need everyone’s contribution to approach the truth.
