I find this plausible, too: I can imagine groups of people getting together recreationally and fantasizing about how they're going to overthrow the fascist mayor, or kill all the Jews, or whatever else. With their real guns and tactical gear, because those look cool. With a badass logo, maybe with some skulls in it. But with no intention of ever actually acting out those fantasies.

It’s a multiplayer game in which players LARP as assassins out to kill targets that they receive secretly at the start of the game.
The game has rules that describe how to simulate various forms of weapons and tactics (e.g. using a rolled-up sheet of paper as a dagger), and the rules are intended to help make it clear to observers that it’s just a game in which no actual crimes are intended, but it still involves people behaving in ways that could be misinterpreted.
I played it some at VCU in the late 1970s. It was fun.
