I think it summarizes the problem of 4chan. It doesn't say anywhere that the media tool the bait and the ADL has an old blog post making it clear that, at the time, it was a hoax. Now the ADL has reclassified it as an actual symbol of hate by alt-right groups and white supremacists.

I think the article paints a picture of the rise of hate groups and the appropriation of a commomly used and innocuous hand gesture. Hell, as a diver, I now have to think about the fact that some Bad Actors have taken what I use to indicate that I'm fine and turned it into "I support genocide."
