Recently the user @Kilisi posted an answer in the link above stating that the OP should have slapped the aggressor back. I feel this is inappropriate advice and have DV. Retaliation as suggested could easily backfire for the OP, and rather than make the OP's position more defensible as an victim of a battery, could provoke more harm.
I also do not understand how the OP has lost face, given he was clearly the victim here of a criminal assault. The advisable suggestion is as @Joe Strazzere wrote in a comment to report incident to the police, and let them take care of it, which is their role as enforcers of the rule of law. The OP as a victim should not have no fear in going the official route. This also creates a documented trail which only further helps if necessary in the future, as to what happened that day.
For this particular user, I have noticed this common theme in many of his answers. A theme of distrust of the established system of law is evident.
How should these types of answers be handled by the SE community?
