Stop the boat for a second.
What does LARPing mean, again? Back in the day it referred to Nordic teens running around in costumes in the woods, playing a kind of improv Dungeons&Dragons. Then it seems to be applied as a kind of defense of the more slimy and despicable conspiracy theorists like Alex Jones, as in, "oh, they're just creating this fantasy world for themselves, they don't actually mean what they say", as if they made up horrible lies about victims of terrorist attacks and school shootings just to pass the time wih their buddies, like when teens in the woods pretended to be elves hunting trolls.
Now you're apparently "Live-action role-playing" [if you] shoot black people in the streets.
Did you mean to use the term very sarcastically/satirically, or is there some other meaning here I don't get? I take it my interpretation above is completely wrong?
