I'm here, so I'll take this one.

How did you insult the man's daughter?  You said, "These 'women' are just as culpable, if not more so, than Mr. Naval."   You wrote, "The end results are telling of the personalities involved. 'Normal' people don't spit their beverage on other people."  You said, "you're naive to suggest that these 'young women' are not culpable," as well as "the antisocial behavior of his daughter who confronts a man, engages in vile and disrespectful rhetoric that culminates in physical violence."

You said, "from the outcome 'talk' was putting their intentions mildly.”  You told him, "your family initiated the incident via a confrontational approach and instead of cowering to your family's vulgar nonsense, he stood his ground and was subsequently assaulted for having done so."

So..  you called his daughter and daughter in law guilty, evil-intentioned, vulgar, violent, vile, disrespectful, antisocial, and abnormal.  Around here, those generally count as insults.
