You have to understand that a lot more goes into soccer, especially during big tournaments like this, than just the game itself. For example, German people (at least up until my generations) did not grow up with a great sense of patriotism due to WWII. Soccer is a huge sport in Europe, and pretty much nobody plays football. Ever since I can remember, during big international soccer tournaments were the only time you were allowed to root for Germany and people weren't ashamed to fly German flags. People came together to celebrate the German team like nothing else.
This is in Berlin:
So, you don't soccer. Millions do. I don't like football and I don't really get it. The games seem way to long and all this stop and go just makes me yawn. Millions find it terribly exciting (for whatever reason). People have tried to explain and bring it closer to you, but you are still just ridiculing it. Just don't watch it then
