That's would be an accurate analogy if you had things thrown at you on a regular basis. Every single professional sport has fans that throw things at players. It is part of the territory. Now, if I was a fan, and that jackass came at me, I would beat the tar out of him, as much as I could.
You're not suggesting throwing things at the players is "OK", are you? Just because they are players they should expect this? Would you dream of walking up to someone and throwing a beer, or anything else for that matter, in their face and just expect them to sit there and do nothing?
Nonsense, you are not paid to take assault. This is not Michigan with the marshmallows, OK?
If you were on the street with your man, and someone threw beer on you at a bar or just on a corner, you'd be MAD if your husband/bf didn't do something about it.
Football players wear padding and helmets. ANd do you not remember when the Raiders went into the stands at Mile High when they had iceballs and batteries chucked at them?
How much is enough?
