Agnosticism is a worthless blight on religious discourse.
How do you figure?
I feel as if "I'm agnostic" is a get out of jail free card in a lot of discussions regarding religion, at least in my experience.
Isn't being uncertain a "get out of jail free" card for any conversation? Does that mean uncertainty is a "worthless blight" on any discourse? Uncertainty is oftentimes the most reasonable option. It's especially defensible, I might argue, on the topic of metaphysics, which as Antonio says is almost definitionally outside the realm of conventional 'knowability.'
Also, how is intellectually unjustified certainty not a much worse blight on discourse than being over-cautious?
