I think the retired USAF Colonel went well beyond simply publishing facts on the internet. It sounds like he made threatening statements.
None of us wants to be sued. PVPS is already costing us a small fortune from lost-time off, meds that insurance refuses to cover, inability to work as effectively as we’d like, etc. For that reason, 99.5% of my posts don’t mention the cruel vasectomist by name, the man who denied ever having a bad outcome and then, later, saying “I send my pain guys to…” some other urologist. My vasectomist said “what do you want me to do, cut off your testicles?” I think reporting facts like all the useless attempts the vasectomists take that waste time and money and show their ignorance are completely fair game BY NAME.
Opinions, name-calling, and saying things like “avoid this guy at all costs” might get you sued.
