The reasons are irrelevant to me. I personally didn't care one jot about what he said, it didn't bother me at all. It DID bother me to hear that it was needed and a good thing that their feelings got hurt. Even if it's over something I personally think is silly or slight, I'd never say that about another human being. It's simply unnecessary. It takes about half a second to think of a way to say all of this in a way that isn't nearly so confrontational about a group of people.
