Us Against Them

We're living in a culture of angry debate, conflict, and taking sides.
People are labeled instantly, opinions are presented as facts, and social
media posts seem to take a stand against everyone but don't convince
anyone. 

As Christians, is it our duty to "take a stand" for the things we believe
in? Should we be entering into the political landscape? Should we avoid
polarizing people and instead just offer grace instead of our opinion? How
did Jesus treat these questions?
