he is not disrespectful.
He is not in a War Crimes tribunal for heavens sake. He is on a track! He is playful, vivacious, cocky, whatever, but he is not disrespectful.
I agree some people will dislike him for this but you can't label him as disrespectful. He is one relaxed, kind joyful dude.
Not even Gay seemes to think so as they shook hands. Otherwise he probably would not have.
