Chans/Voat make joke posts about fictional racist fetishes. For one, milk.  They all talked about how milk was the chosen drink of white supremacists because it was homogenized and pure white.  News outlets picked up the story and ran with it - no joke, search "milk racism". They decided to see how far they could devolve the idea while still having SJW liberals believe it and spread the stories via social media. So they decided on the most neutral thing they could - the OK hand sign. In satire, they said that the three fingers sticking out when you make an OK sign is for "W" and the loop you make for the O is actually a "P" when connected to your middle finger. So instead of saying "OK" you are saying "WP" or "White Power". The news fucking believed it.  It was posted all over that if you make the "OK" hand signal, you are making a "White supremacist dog whistle" to silently signal to other white supremacists. It got so out of hand that people have been banned from baseball stadiums, libraries, etc..., and fired from their jobs just for making an OK hand sign. What a bunch of dumb, gullible, sheepish, wolf-crying, strawman-fighting pussies modern liberals are!
