It is almost as if you are asking if a war is coming.
"The left and the right. We hate each other. But are we close to that time when hate turns to killing? I believe we are already seeing the left engaging and murdering the police. We have an enemy media that lies day after day.
But are we close to taking up arms against one another?"
