I don't think there is anything "bizarre" about giving a definition of a legal word, explaining how it's used, and then stating exceptions to the rule. Of course a statement is not hearsay unless offered into evidence for the truth of the matter asserted. I am not sure your point there as I never said anything different.

I said quite clearly one can be charged with perjury if they lie under oath and then made clear that hearsay is a statement not made under oath.

Breach of contract in an email? Generally not, there has to be some actual act or threat thereof.

I'm pretty sure we're on the same side here.
