... In case you aren't aware, naming names limits what you can say without legal repurcussions. By keeping the name out of it and being vague enough that the discussion doesn't reveal the shop it allows us to be more blunt, express our personal opinions, and not do real or perceived damage to the LDS. Trust me when I say that no business can do this to it's customers and stay in business.
Disclaimer: I am not licensed to practice law in your jurisdiction. As someone who graduated from a top 100 law school (at least at the time I entered, LOL), I was under the profound impression that truth is an absolute defense to defamation in all instances. I was under the impression that the damaging nature of the comments is irrelevant if you don't meet
all of the statutory elements for the cause of action suit is brought under (e.g., libel - written defamation).
Even Wikipedia has the basics of defamation down pretty well IMO. "Under United States law, libel generally requires five key elements. The plaintiff must prove that the information was published, the plaintiff was directly or indirectly identified, the remarks were defamatory towards the plaintiff's reputation, the
published information is false, and that the defendant is at fault." (emphasis added)
Also, I haven't researched the issue in the least, but if memory serves me correctly, it's much harder to prove defamation of an entity (e.g., LDS) than an individual. Perhaps tortious interferance would be a fallback claim for them. All the same, acting in good faith by exerting your first amendment rights while stating something which is true will rarely, if ever, support such a claim. Truth is really the big element here too. That said, I am not licensed to practice law in your jurisdiction and haven't researched the matter recently, so take the above as my personal (not legal) opinion.
