and that he apologizes for hurting her. He could have even got away with saying he didn't intend disrespect but the comments are obviously hurtful.

I think in general people don't know how or are willing to apologize when they make a mistake. People make mistakes. Adults realize when they do, make amends to correct or end the behavior, and repair the relationship with the person or group who was offended. Making a mistake doesn't mean someone is inhuman. Doubling down on the mistake makes someone immature and reflects poor judgement and character.
