It's not just that he slapped a smaller man he slapped a smaller man who didn't go down. If you are going to deliver an open hand slap unblocked instead of a punch because you outweight them by 50lbs then you better fucking drop them. Honestly an open hand slap is easier to throw hard and aim more natural than a hook but slap they don't go down and you turn and walk away wtf is that? You want to throw hands stand and wait for them to come back. Hitting a smaller man on stage you know won't fight back and has his hands in his pockets so you can casually walk away is a coward move.
