No. It is about sitting next to some jerk, even if you accompanied them to the game and getting hit by a chair someone else threw at them. It is about paying money to be at an event and being assaulted by one of the people you support by being there.
It is about a two-tiered system of behavioural expectations which goes back to the days of college athletes being treated better than those lowly slobs who were just there for an education.
flog the jerk (the one who threw the chair).
If a spectator had thrown a chair and broke the player's nose, we would be hearing a different story. We shouldn't.
There you go!
( And i like the bit about flogging!)
