When someone says something offensive to you ... it seems like you should be offended by that. ... to the extent that you can shape your reactions (or character traits), this seems like one you'd want to keep.

His examples were cases where we might want to keep the reaction. But that doesn't mean he was talking about "objecting to harm" instead of offence, as you suggest. He was just using the most positive examples for his argument.
