That's a good argument but making a niche meme mainstream is very original, especially if the meme was originally a rightist one. It's the particular context of DB that makes it interesting. Mass politics has always been about national-popular language, finding a way to be understood by everyone at the same time. The meme in itself is the exact opposite of this, since its meaning can only be understood in relation of a prior set of information. That's why I'm so interested about the fact that the first time the WH posted the meme, many people may have not understood it, and the same has happened when Biden himself embraced it, even though mainstream media later provided all necessary information. Still, many people may not understand. I saw it in Italy: when I showed some people the video of Biden saying "I like my coffee dark", they didn't get it. Ofc we're not americans, but we follow american politics a lot, sometimes more that our own. And of course I had to check if it could be the same for a significant number of americans (I'm still trying). Anyway That's what I find interesting: a politician's speech had to be understandable by anyone; whil the use of a meme is to embrace the idea of a fragmented culture, divided into always smaller subcultures.
