I ve always said her reaction is understandable and the man honestly needs something more corrective that a pair of umbrella attacks.
Its good that she took a stand, it would actually have been wrong (but understandable) that she didnt.
I have said since I saw the video that the scandal an any violence fir the direct removal of him of her space is justified and was needed. The part I see as non justified was the violence peroetrated after she had already removed him. Scandal could and would have much better be if had continued on as loudly as possible for as much time as possible, but you can continue it without the violence.
In other words, I dont think violence is the only way to take a stand, and given she had already used the violence necessary to remove him from her, the violence that comes after that is what I dont deemed justified, although I would say its understandable.
After having his immediate threat removed, violence is not the only way to take a stand indeed. But i also think that what she did was justifiable. The method of choice to send the message in question (if that is what she had in mind) is fine by me so long as it doesn't victimize the man, in the sense of doing to him something unwarranted or undeserved by his actions. In addition, as already mentioned repeatedly the threat here is a bit complicated and thus we can certainly allow for the possibility that what she did was perceived as necessary to assert dominance.
In the context, and considering all possibilities, i don't feel anything but being glad he got his *** kicked and that the woman seemingly succeeded in both defending herself and possibly making a stand for herself and other women.
