The image was used as an Internet meme that was dubbed “sad frog” when it first popped up on 4chan (what I like to call the open sewer of the Interwebs), but eventually became the apparent symbol of the “alt-right”. The character earned its label by being associated with anti-Semitic posts around the Internet. ADL added the ‘(((echo)))’ symbol to it’s list of offensive symbols earlier this year.
I wonder if the Anti-Defamation League knows about 4chan. They’d probably be incensed.
