People in this thread are seriously misunderstanding what the ADL list is about. It's not supposed to be some kind of list of banned symbols or something like that, it's supposed to be a list of symbols that can be used to identify white supremacist people and organisations, because not all of their symbols are as blatant as the swastika.
Because they're so stigamatized, white supremacists form a somewhat hidden subculture that rely on dog whistles and abstract symbols to identify each other. Stuff like "88" or that triforce-looking thing are part of that. They're not inherently evil or something but if they use them the right way they can broadcast their allegiance without overtly revealing it to people who aren't white supremacists.
Pepe has been co-opted as one too - when used in specific contexts. Trump Pepe is one such context, overtly racist Pepe memes obviously another, and even heavy use of ordinary Pepe memes in say an otherwise very racist twitter feed can function as one too. Does that mean you should stop using Pepe memes because they're forever taboo now? No. Just recognise that they are being used as a dog whistle as well, and be a bit careful about not accidentally coming off that way - for your own sake, if nothing else.
