Thank you for saying this. For a community that prides itself on rationality, it's insane that every single issue needs to be relitigated from a position of absolute ignorance. Every "prior" needs to be set at 0.5, right?

While I enjoy the technical expertise that I often find on HN, I'd be more inclined to actually talk about issues like sexism, politics, etc. if I didn't have to start by answering questions like, "is sexism even real?", "was slavery so bad?", "H1Bs are indentured servants", etc.
