It's funny how memes mutate. In The Matrix, the difference between red pill and blue pill is whether or not you know you're in the Matrix. It's a 'fruit of the tree of knowledge' metaphor. It's logically impossible to both know and not know, so it's a hard binary.
But given the way the terms have been used as memes, "purple pill" totally resonates as shorthand for transcending polarisation 😏
