Thank you for the clear example again, Mike.
(case a: ",conj (b)" included) There is deep suspicion that government is the natural enemy of freedom, even if it is elected by the people.
The truth is that a person of seventy is a totally different person than a person of twenty ,and a comparison or their intellect is impractical. (case b: ",conj (b)" excluded) I have a deep suspicion that government is the natural enemy of freedom, even if others disagree with me.
The truth is that I was home alone on Saturday night, and I hope you believe that.
Now, which case is more common, "case a" or "case b"?

So I thought "case a" was more usual. But it seems like you are saying that "case a" and "case b" would equally appear in English, depending on the content.
