The 'You Are Not Immune to Propaganda' meme features a pixelated image of the comic strip cat Garfield staring blankly into the distance. It originated on Tumblr in 2018 when a user combined the phrase with the feline's likeness to create a meta-commentary on the pervasiveness of media influence. The image quickly became a staple in online discourse, used both ironically and seriously to remind users that everyone, regardless of their awareness, is susceptible to psychological manipulation and advertising. Its enduring popularity lies in the contrast between the heavy, philosophical message and the mundane, cynical nature of Garfield himself.
