One thing I learned in Europe is to discuss politics over food.

Food is like CS Lewis said about smoking a pipe: It gives a wise man time to think and a fool something to put in his mouth.

What that means is that people get to spend time thinking before they respond and that makes a big difference. When I did a contract in Denmark we used to discuss all kinds of politics -- immigration, cultural differences, which parties were insane, etc but always over food. And it meant we could discuss and disagree without feelings getting hurt.
