So here's a question: while this subreddit is applying the idea of the red pill to gender relations, I think the broader idea of the "redpill" outside of just that realm is also interesting.

IE, a "redpill" being some piece of knowledge that reveals a truth that can't always be spoken in polite company, at least not directly.

So given those parameters, what are peoples favorite non-/r/theredpill redpills?
