And I will just say this on the "Slap heard round the world", both parties were wrong. However I can understand how a person might react in that way when someone is trying to poke fun of a loved ones aliment. My understanding is this isn't the first time the two had beef with each other.
I keep seeing people say both of them were wrong without qualifying that statement (due to different biases) and I think that’s kind of crazy. One is a comedian who made a very mild joke. The other slapped someone on Live Tv.
