I really disagree. The event should be judged, not the context. A red card tackle is a red card tackle whether it's after 3 minutes or 89 minutes. A bite is a bite. Should be the same punishment for a Premier League player or a Conference player.
I suspect the comment referring to twitter is one measure of how the act affected the image of the game. Doubt it was much of an influence in the decision though.
Quite frankly there should be more consideration of the public response and image of the game when punishing these animals. It's a form of entertainment, one of the most important on the planet that influences millions. These brats need to understand that when they go on the field they are role models only employed because of the public's money and thus they must behave. If they can't do that, then they should be out of the game. Sod off and do a job where there is no public limelight and you are aren't shaping minds.
Whether twitter is a great way of measuring the public response, I don't know. Wouldn't base decisions purely on it, but social media definitely has a role IMHO.
