The ADL considers Pepe a hate symbol, which I agree with is daft but that’s kind of key to their data and they are considered experts in the field by most. They scanned Steam with some automated tool looking for hate symbol images, came up with like a million hate symbols detected. If something contained more than one detected hate symbol, it got counted as however many hate symbols the tool detected (so for example Pepe saluting a swastika would count as a Pepe and a swastika).

Almost 55% of those were Pepe. The next highest was the swastika at 9%. A literal majority of hate symbols they detected with that tool were Pepes, at more than 5 times the rate of the next most common symbol. It’s literally included to make the problem bigger in the hopes that most readers either won’t look that deep or won’t know what Pepe is.

EDIT: Another fun one is if you go look at their hate symbol index, about an eighth of two digit numbers are either hate symbols or part of a hate symbol.
