Thank you, Forlorn, for your explanation. Much appreciated. Though I must say that I still needed to decipher some of the language you have used even in this explanation. Sometimes I feel like I have fallen down a rabbit hole, like Alice. It is all so foreign! I need to employ an interpreter, what with 4chan, red-pilled kool-aid, normie. I'm not meant for this world!
4chan is just an anonymous messaging board.
Redpilled is a tougher one to explain. Someone might call themselves redpilled if they think they can see through lies about the world that "normies" accept and believe. It's mostly used in reference to race or the Jews. If someone says they're "redpilled" on the Jews, it means they believe in the Jєωιѕн conspiracy. One could say they were "redpilled" on Vatican 2 if they realised it for the heretical council it really is and not some "vibrant progressive council" nonsense that most believe.
The term comes from the film "The Matrix" where the protagonist could take a blue pill and live in blissful ignorance, or take a red pill and be shown the horrible truth about the world.
Drinking the koolaid comes from a cult in the 70s I think, that committed mass ѕυιcιdє by drinking poisoned koolaid. Drinking the koolaid refers to blindly following/believing someone against all rationality.
