LongHairGal: I saw something very like that. At the time (70's) I was in the Pullman, WA congregation. We had a visiting speaker from some tiny town in Idaho. That Congregation probably hadn't seen a new person in a decade or two. Speaker made a snide comment about Catholics that would have gone unnoticed in his own congregation. Unfortunately one of our pioneers sisters picked that day to bring her (Roman Catholic) study to the Hall.
Study was offended and left in huff during the song between talk and Watchtower study. Pioneer was seriously ticked off, after the meeting ended the elders had a meeting which ended with a letter to the Idaho congregation telling them to not send that guy to speak at our hall. Ever. I heard through the grapevine that the visiting speaker never did understand what he'd done wrong.
Another perfect example of how insulated JW's are. That was not the last tone deaf thing I heard from a witness, not by a long shot. For that matter I heard similar offensive remarks at a main stream church, before I stopped going to religious meetings entirely.
