So the guys' daughter made a public rant, he considered it unacceptable, but he then turned around and basically did the very same thing himself? I wouldn't necessarily say that he was setting an example for anyone.

Wouldn't a more appropriate/adult response have been for him as the parent to speak with her privately one on one about making such information public? That's just my opinion though because communicating via grape-vine as it were ( in this case responding via Facebook/Youtube videos) is one of my personal pet peeves as it becomes less like actual communication and more like a public relations contest where both people are trying to prove they are right by rallying whoever may be listening to their "side".

What happened in this case is simply not adult-like communication in my opinion and the father should have known that. There's more to being considered an adult than just age. I don't even have children and I know that.
