This person lives and breathes politics, he is a political blogger. Just interacting with people outside of politics was new for him.

He isn't saying 'ignore politics', and he isn't saying 'we can all agree on everything'. What he is saying is 'making your life about political issues distorts your perspective to where you think that everyone hates one another to point of declaring a civil war' and is advocating sitting down and just socializing with people without the baggage.

As the kids say 'its not that deep'.
