why the Nazgul are a bunch of pussies

In everybody's favorite, lord of the rings, we find our valiant hobbit friends out and about in Bree, land of the not hobbits, when out of no where Frodo gets stabbed by a black cloaked man, people are under the misconception that the Nazgul could have killed all of them if it weren't for Aragorn, but they are wrong. Frodo, naturally as a hobbit had the power of ten Nazgul times Sauron, was clearly holding back and allowed himself to be stabbed so he could become immune to the poison they were armed with. Everybody knows that the hobbits only weakness is the poison dagger, and now that Frodo is immune to the poison he is now immortal.
