Some common sense is logically sound (based on deductive reasoning) and some is not (based on (usually strong) inductive reasoning).
As for your strict-construction-based definition of "common sense", I think that you are using the wrong sense of common and sense and are arriving at the wrong definition. Webster's defines the phrase as "sound and prudent judgment based on a simple perception of the situation or facts". This would fit a definition deriving from what a common person (i.e. not an expert) or a person with common knowledge (again, not an expert) would conclude is reasonable, or makes sense, to believe based on what he observes in everyday occurrence. "Horse sense" is a synonym for "common sense" -- even a horse knows these basic things.

My advice to fanboys: Brag about stuff that's true, not about stuff that's false. Predict stuff that's likely, not stuff that's unlikely. You will be happier, and we will be happier.
