I get what you're saying here, and on one hand I agree - getting a suspension just for flipping out on somebody in a non-violent and non-criminal seems silly.
However, on the other hand, when you're working for a media giant like ESPN, and your behavior casts a negative light on the company, I feel like the company reserves the right to suspend you. It's not like she was arrested, it was a private company deciding to suspend one of their employees. They are simply protecting their brand to a degree.
I guess I can see both sides of the coin. I wouldn't have been upset if she wasn't disciplined and I'm not upset that she is either. If anything, think of the suspension as recompense for the verbal onslaught the other person had to take.
