Because you know, the best way to get someone to raise their fist to your cause is to corner them, surround them with an angry mob, shout obscenities at them, flip them off, and threaten them...all while they are just trying to privately enjoy a meal and peacefully exist. She should have raised her fist, and then raised her middle finger to them while it was up. But, then they really would have been able to twist it into something racist so she handled it very well. Props to her, she is a better person than a lot of other people would have been.
