No, that is being contrarian for its own sake. OP specifically said that they don't bother to look at or understand the actual research - that's not what a skeptic does.
I suppose I believe it's less important whether or not we collectively determine the correctness of the other person, and more important that I use their contrarianism to question my own knowledge. I'm less interested in judging their argument and more interested in using their comments to evaluate my own. Kind of a "less wrong" approach, but focused on my own model of reality.
