I might be off-base, but I feel this is a very American thing to do: argue. In school there a even debate classes yes?
Much better, I think, is to have a truth finding conversation together. Perhaps coming from different sides of the story, but always on the search for trying to find common ground, the truth, science, and an open mind to be changed by those things.
And not see the whole thing as a match to be won you know?
