I have a hard time equating the display or firing of a gun with promotion of violence but context makes a difference. Same thing with baseball bats. Both are used in competitive sports or could be tools for killing/maiming others. It’s performative and pandering but not necessarily violent without more information.
Son of a Bitch of Sam, Al Canine and the BTK (Bacon, Treats and Kibble) killer lock their doors at night in case this shady character is out for a prowl.
