I think I have it figured out.
Just like the term Peace does not mean the same thing to Communists (absence of resistance to Socialism) or Moslems (submission to Islam and Sharia), the term Gun Violence does not mean the same thing to Progressives that it does us.
To a conservative, gun violence means the criminal use of firearms against innocent victims. To a Progressive, gun violence means the use of firearms against THEM. That also explains the recent warning against violence by the extreme right that was issued by think tank associated with West Point.
So, one wonders what Progressives might be planning to do that might incite gun violence against them or by the extreme right.
Generally, if someone wants take your firearms away, they are planning to do something to you that you would those firearms to resist...
