old-school tinfoil hat time here
(And believe me, a tiger head requires, like, a whole roll of the stuff....)
What if the (4,8)channers are deliberately trying to persuade the left that AS MANY THINGS AS POSSIBLE are right-wing dogwhistles, from the OK sign to all ten digits, as a willful attempt to culture-jam us into total paralysis?
Mind you, the following sentence is the weakest possible evidence and should never be taken as proof of ANYTHING, but... "I wouldn't put it past them." (I mean, seriously, that's precisely what the OK sign thing is—they've openly TOLD us as much. And yet we still keep walking right into it.)
And if that's not what they're doing... should we maybe be trying to do it to them? 😈(Honestly, I fear they might actually be too far ahead of us on the Meme Warfare tech tree. We gotta up our game.)
