Look at the tv ads that show guns killing lots of people.
Hollywood promotes violence all the time.

The pertinent fact here is that the producers of this movie are advocating targeting a specific segment of society for their pro-America views. Most violent movies just pit bad guys against good guys, and do not seem to be advocating the elimination of a segment of the population.
There is a concerted effort to demonize people for standing up for American values. The encouragement of lunatics to take the next step, ridding the country of these people they have been conditioned to believe are subhuman, has been going on for years, but is becoming more blatant than ever.
The current behavior of the left is quite analogous to the behavior of Nazis and Antifa in pre-WWII Germany. They started by demonizing one group of people and scapegoating them for all societal problems; from there, they started harassing people and destroying homes and businesses. I pray that we do not see our left take their violent tendencies to the next level as the German leftists did. They are certainly capable of it.
