Might want to check that belief with your attorney =>
In the common law of libel, the claimant has the burden only of proving that the statement was made by the defendant, and that it was defamatory. These things are generally relatively easy to prove. The claimant is not required to prove that the statement was false. Instead, proving the truth of the statement is an affirmative defence available to the defendant.

Maybe, maybe not. It is more ambiguous than that when you look at the actual law, especially state by state.
Of course, this was expressed as an opinion and there is no damage, so it is all rather moot.
