If we all know that "that" conversation with the "crazy" uncle is going to come up on Thursday, why do we keep letting it happen?

We know we don't agree, we've seen it happen before, and yet the scenario repeats itself. So frequently in fact that the idea of Thanksgiving dinner with family has become known for the inevitable tension rather than gratitude. Could there be a different way?

We know we won't change his mind, so what could we do differently this year? Could there be any path forward that might leave us thankful for a meal spent together?
