It surprises me that I seem to be the only one on this thread who understands that this is all the result of a 4chan hoax.
4chan is conservative. Its members are wizards of the internet. Operation O-KKK was one of their hoax masterpieces, though it may have evolved in a way they did not intend.
This piece by the Anti-Defamation League provides a good explanation.

Perhaps I was mistaken when I said Reddit and 8chan instead of 4chan but I have made repeated posts about it being a prank.
I should have said in #46 that I have no idea if the ADL’s description of the use of the OK sign among actual white supremacists is accurate, or just reflects the ADL’s agenda. The left adopted and spread 4chan’s hoax, before and after they knew it was a hoax. I do not know whether or not it was subsequently adopted by actual white supremacists. My knowledge of actual white supremacists is nil.
