"Inciting Violence" seems a bit of a catchall phrase, and open to how you personally work it into a situation.
for example, things that may incite violence:
Piss poor referees in football matches
Constant phone calls from energy advice companies (and others)
Boxing promoters (because sport is watching two people batter each other isn't it)
Weapon Manufacturers (go on, tell me it's just for defense)
Neighbours that have outside parties until 2am
Little scrotes that tell you to "F off Gramps" when you catch them looking a little too closely at your car interior
I could go on
