Well I have to say, off the bat, it needs to be not just leftist/marxist. It would need to have large non offensive use in general discourse.

Again my example of pepe for general discord moderation. It's not trolls that show up in say political discussion groups. It's trolls that show up in random game discords or other non-pollitical locations. IE as a moderator I'd also be auto banning someone bringing up random arguements on how we need wealth re-distribution, not because I disagree with them, but because people are just there to talk about a game, and not have political arguement.

and in short that's generally the thing, IMO Pepe isn't... really that overwhelmingly good of a meme where it's just a universal funny to outside groups. But the alt right is the only ones bringing it into more general average Joe locations, along with their hateful rhetoric.

In short for pepe to be recovered it needs... major mainstream Apolitical usage, which quite frankly I don't see often.
