this isn't even remotely true, not under any legal jurisdiction, self-defence is the application of justifiable force against an unjust threat. this is the underlying rational of the defence and is pretty much the same where ever you look. so in that her attacking him and him being literally surrounded his actions were totally justified
Again, I didn't watch the video, but my point is a Slap is less than a Punch. If he was only slapped, then, if he punches, that's escalation, not rational or justifiable defense. So him trying to punch her for her slapping him is not self defense, even by your definition above. He could SLAP her back, but not punch her back.
And if the slap/punch were between her and him, then him being surrounded doesn't have anything to do with it. If he tried to punch the people surrounding him, then that's different, but that's not the impression I got from the other comments here on the Escapist. Again, since I'm ONLY replying to the comments here on the Escapist, I may have an incorrect impression of events, but that's all I've got to work with at the moment.
My point is, getting slapped isn't anything that needs "self defense" - it's not a threat to one's person. The rest, maybe, but a slap? No.
