the thing is, she didn't try anything. self-defense doesn't let you preemptively attack someone because you think they might be a threat. she was posing no reasonable threat in that situation. other people doxxing him and issuing death threats doesn't give him the legal right to assault anyone who knocks at his door. if he asked her to leave first, this would be much different. but ambushing someone at your front door like that is plainly illegal.
