*nods* I honestly don't think most of these folks even know what solipsism is in the first place to have any depth of thought about it. It's not exactly the sharpest tools in the shed we're dealing with.

In terms of doubt, I tend to view truth and doubt as being reciprocal. Doubt is custodian of truth, in that it constantly refines our sense of truth and guards us against falsehood. Take for examples the scientific method (falsifiability/falsification), or jurisprudence (presumption of innocence), etc. Truth isn't really a fixed mark, but an ever receding horizon, with doubt being the wind which propels us perpetuation towards it.
