Walmart was selling what I believe to be a genius idea: half of a pumpkin pie combined with half of a pecan pie. Instead of forcing people to choose one over the other – or to buy two pies – they made it easy to have it both ways.
Use that split pie as a metaphor for your holiday conversations. Politics has added a new layer of tension to family gatherings, but instead of arguing over who is right or which is best, find a way to accommodate both flavors. You can allow the two different sides to coexist without a unanimous point of view. Try to compromise enough to allow everyone to enjoy their holiday.
