You're over generalizing. There is a lot of circumstantial evidence that help make evolutions case, but that doesn't make it fact. In the same vein that those that don't believe in God say they want physical proof that God exists, I would say that I will say that evolution is undeniably true if a monkey walks out of the forest and starts a conversation with me. Believe evolution if you want to and I won't denigrate or think you're dumb. I just would like the same treatment.
