Dr. David Jones was making his morning rounds at the hospital and his last patient to see was Jeff Stone. Mr. Stone had been transferred out of ICU (Intensive Care Unit) to a private room in the very early morning hours as he was recovering from COVID-19. In the private room were Jeff's family members. After Dr. Jones examined Mr. Stone, Clyde Stone posted a rating on Rate Your Doctor.com. Clyde gave Dr. Jones a very low rating in bedside manner due to the fact that Dr. Jones seemed irritable and said "I would have been in to see your earlier, Mr. Stone, but when you were not in ICU, I had to spend all my time finding out if you were transferred or had died." Dr. Jones added: "Many, many COVID patients don't make it out of the hospital alive." Clyde looked at Dr. Jones and said "Well, I think this is a much better alternative for my dad, don't you think?" Dr. Jones learned of the post and filed suit claiming that Clyde Stone defamed him. What defenses to defamation would Clyde Stone have? What would Dr. David Jones need to prove in his case? Explain.
