I'm afraid that VP has fallen into the trap of thinking that all opinions are equal, whether they are supportable by fact or not.
VP, there is nothing wrong with offering an opinion. But it is wrongheaded and willfully ignorant to insist on pushing an opinion that has no evidential support.
Every time you do this you lose credibility, not that you have much left any more. It's unfortunate because you don't come across as stupid, just stubborn and defensive. And as an occasional liar, which doesn't help either.
Muttley has no vendetta against you, but you can be sure he's fact-checking you and calling you out whenever necessary. If that is offensive to you then you are the one with the problem.
