Ah. I don't really see how making fun of people who performatively support popular causes is relevant here, but I suppose memes move in mysterious ways. Perhaps it's assumed that because this may become relevant, actions against monkeypox will surely get performatively supported? But then, I'd say that pre-emptively aggressively opposing that is only going to make it more likely, not less, that this becomes some kind of a "culture war" issue that gets performative support. (As any teenager knows, an ostentatious roll of the eye at the other side only intensifies the argument.)
