>>8301715"Redpilled" means you are aware of the truth, and realize you have been lied to from the very day you were old enough to understand the words of the lie.
Every human on Earth has been lied to their entire lives, about almost everything. If you "take the redpill" you finally understand this, and it is the first step in trying to find and analyze the truth, and understanding reality.
Normies ignore the redpill, because the lie is far more comforting to them, and it means they don't have to do any work to find the truth. They feel secure in their web of lies, like they are wrapped in a blanket, but it's really just a spider-web sack, and the spider is feeding off them.
