So then what? The ballpark shooting is now justified based on what you're alluding to? Which then inevitably leads to a retaliation that is justified by not words spoken, but the shooting itself? If the answers to your questions justify shootings, the shootings have to then justify an escalation in violence right?
Those using shootings to score political points or thinks they're evident of the left or right as a whole should maybe think that instead they are evident of two sides of the same coin, they're a symptom of the same disease that is political extremism. Whether we self identity as being somewhere on the left, center, or right of the political spectrum we gotta have more common ground with each other than the extremists that think their violence is justified?
