Can you not see how booing to throwing things is not that far apart. How is booing not threatening also. Of course it is, but hey its ok cos my team is playing bad. Did you ever see english soccer when they put fences all around the grounds because booing went to throwing and violence.I diasgree, booing is fine IMO but expletive laden rants are too much. Throwing objects and or threatening behaviour is clearly unacceptable and what I saw made me uncomfortable and sad.
The passionate mob mentality is all always sad.
